1986-05-18  Richard M. Stallman  (rms at prep)

	* alloc.c (malloc_warning_1): Add some advice on
	the significance of the warning.

1986-05-09  Richard M. Stallman  (rms at prep)

	* sysdep.c (get_screen_size):
	Reject values of TIOCGSIZE if they are ridiculous.

1986-05-05  Richard M. Stallman  (rms at prep)

	* process.c (send_process_1):
	If pipe buffer is full, wait a second and try again.

1986-05-02  Richard M. Stallman  (rms at prep)

	* termcap.c (tputs): round rather than truncating
	when dividing padcount.

1986-04-24  Richard M. Stallman  (rms at prep)

	* insdel.c (del_range): args passed to adjust_markers
	are now properly adjusted for the gap.

1986-04-20  Richard M. Stallman  (rms at prep)

	* alloca.c: Declare xmalloc.

1986-04-17  Richard M. Stallman  (rms at prep)

	* filelock.c (unlock_buffer): New function to unlock
	a specified buffer.  Use in Fdelete_buffer_internal
	to avoid lossage if buffer being killed is not current.

1986-04-14  Richard M. Stallman  (rms at prep)

	* alloc.c (malloc_warning, Fgarbage_collect):
	If malloc_warning is called during GC, just save warning
	in malloc_warn_string.  Try again to warn when GC ends.

1986-04-12  Richard M. Stallman  (rms at prep)

	* m-celerity.h: Remove spurious effectless #define BSTRINGS

1986-04-10  Richard M. Stallman  (rms at prep)

	* xfns.c (Fx_get_default):
	Avoid doing strlen(value) if value is 0.

1986-04-08  Richard M. Stallman  (rms at prep)

	* indent.c (compute_motion):
	Change unsigned short back to short.  unsigned short is plain
	wrong and causes infinite loops when horizontal scrolling is used.
	Introduced macros HPOS and VPOS for extracting components of cpos.
	Alternate HPOS definition for Celerity since casting to (short)
	loses there.

1986-04-07  Richard M. Stallman  (rms at prep)

	* dispnew.c (update_screen):
	Don't zero OPhysScreen and DesiredScreen until after
	final error check.  Omit the error check unless debug_end_pos.

1986-04-06  Richard M. Stallman  (rms at prep)

	* cm.c (calccost):
	Was returning garbage if arrived at fail: by goto fail;.

1986-03-27  Richard Mlynarik  (mly at prep)

	* dispnew.c:
	Typo: `#ifdef defined...' => `#if defined...'

1986-03-26  Richard M. Stallman  (rms at prep)

	* doc.c (FSnarf_documentation):
	Appending the arg to the file name must be done
	whether or not CANNOT_DUMP.

1986-03-25  Richard M. Stallman  (rms at prep)

1986-01-21  Richard M. Stallman  (rms at prep)

	* keyboard.c (kbd_buffer_store_char, fake_suspend):
	Take the STRIDE code for subshell out of kbd_buffer_store_char
	and call it fake_suspend.  Call it from previous place and
	also from Fsuspend_buffer, on all systems that lack SIGTSTP.

	Don't include sgtty.h; no longer needed.
	Make use of wait3 depend on existence of WNOHANG.

	Have and use pagemask to round data_start in COFF case too.

	it is not provided as a system call.
	This takes care of the STRIDE changes for unexec.

	* ymakefile:
	Give ld the arg $(STARTFLAGS), and define that based on cpp macro
	TEXT_START_ADDR when that is defined.  This is for systems where

	(Prevent a_bss from being negative).

	* casefiddle (casify_region):

1986-01-19  Richard M. Stallman  (rms at prep)

	  sysdep.c.
	Changes for STRIDE micro

	emacs -- perhaps this is a reasonable thing in all wimpy unix
	versions.

1986-01-10  Richard M. Stallman  (rms at prep)

	* dispnew.c (update_line):
	Don't consider spaces at beginning as special if line is
	highlighted.
	Avoids losing the inverse-video on leading spaces in mode lines
	on terminals where erasing does not turn on highlightig (vt100?).

	* process.c (pty):
	On UNIPLUS, don't try opening other side.

	* filelock.l (lock_file_1):

	* fns.c (merge):
	Don't assume args are consecutive; GCPRO each one separately.

	* insdel.c (make_gap):

	new desired amount of gap.  Wasted a lot of memory!

	* alloc.c (malloc_warning):
	Passing Fprinc to internal_with_output_to_temp_buffer
	loses since Fprinc needs 2 args.  Use intermediate
	function malloc_warning_1.

	Handle keyboard macros (symbols with strings as definitions)
	with a canned string.

1985-06-05  Richard Mlynarik  (mly at mit-prep)

	If wait_reading_process_input returns and kbd_count stil 0,

	Change kbd_buffer_get_char never to return -1;
	kill emacs on eof in batch mode, abort on eof non-batch.

	* keyboard.c:
	Eliminate dribble_count.  fflush (dribble) after each char.

	try converting to lower case and look again.

	* data.c (listp, nlistp, eq, null):
	Use EQ or NULL rather than old slow comparisons.

	* data.c (symbol-function, symbol-value):

	* minibuffer.c (read_minibuf)
	Added variable enable-recursive-minibuffers
	(enable_recursive_minibuffers) so that Real Men may confuse
	themselves.  (Some commands such as c-h f can also use it) (This
	is not quite the right thing for commands to bind to read their
	arguments since it enables arbitrary recursiveness, not just one
	level to read args)

	* buffer.c
	Wrote generate-new-buffer --- like gentemp for buffer names.
	Rewrote create-file-buffer into lisp code in lisp/files.el

1985-05-27  Richard M. Stallman  (rms at mit-prep)

	Define tt.t_padspeed, minimum speed at which padding needed (pb#).

	* Trm*.c, dispnew.c (Ding):
	tt.t_flash is always set; it flashes the screen or beeps using `bl='.

	* TrmTERM.c:
	Use `IC', `DC', `rp' and `bl' termcap strings when appropriate.
	No longer look for nonstandard `nn' or `rn' flags or `ds' string.
	Do not assume ^M and ^J can be used unless `cr' or 'do' or `nl'
	says so.
	?? Make second arg to tputs always number of LINES below cursor
	because the termcap documentation says so.  Is this right ??

1985-05-24  Richard M. Stallman  (rms at mit-prep)

	* keymap.c (push_key_description):
	Use DEL for 0177, RET for 015, LFD for 012, TAB for 011, SPC for 040.

	Increment new variable num_input_chars on each call.

	* All .h files: make all variable definitions `extern'.

	* buffer.c, window.c, xdisp.c, display.c, dispnew.c,
	syntax.c, fixedpoint.c: Put in one non-extern definition
	for each variable that used to have them only in the .h files.

	* keyboard.c:
	Refs to Cant1WinOpt should say windows_or_buffers_changed.

	* buffer.c (kill-all-local-variables):
	Don't clobber a variable currently set up for some other buffer.
	Was losing the other buffer's recent setq's if the other
	buffer had the same variable local.

1985-05-23  Richard M. Stallman  (rms at mit-prep)

	* buffer.c (list_buffers_1):

1985-05-21  Richard Mlynarik  (mly at mit-prep)

	* The documentation for substitute-command-keys was fazed out by
	its own hairy heuristics!  Moby quoting (past the c compiler, and
	then past substitute-command-keys) added.
	People should be careful of this.  Also, hacks which make
	printed documentation out of doc strings need to know about this
	cruft.

1985-05-21  Richard M. Stallman  (rms at mit-prep)

	* TrmTERM.c, dispnew.c, cm.c:
	open-termscript opens a termscript file,

	Open code the loops that trace function definitions of symbols.

1985-05-19  Richard M. Stallman  (rms at mit-prep)

	* buffer.c, window.c:
	Change algorithm for reordering Vbuffer_alist:
	select-window now calls record_buffer.
	other-buffer now prefers buffers not visible in any window.
	bury-buffer, which puts a buffer at the end of the list,
	is now defined.

	* keyboard.c (get_char):

	Turn on alternate keypad on entry, turn off on exit.

1985-05-16  Richard Mlynarik  (mly at mit-prep)

	* fileio.c: added optional third arg ok-if-exists to
	rename-file, make-symbolic-link, add-name-to-file and copy-file.
	If the destrination filename exists, then if ok-if-exists
	is non-nil it is silently bashed; else if the function was
	called interactively the user is queried as to whether s/he
	wants to bash the file; otherwise (ok-if-exists nil, non-interactive)
	a  file-already-exists  error is signalled.
	
	* window.c: made get-window-buffer return nil if get-buffer of
	its arg returns nil, rather than erring.

	not yet reclaimed by gc, including dead buffers.

	* read.c:
	Fix up register declarations.

	Define -batch switch: do no redisplay, don't change terminal modes.
	Lisp variable `noninteractive' is non-nil in this mode.

	* syntax.c:
	Made most scanning loops turn on immediate_quit.

	* eval.c:
	Fsignal clears immediate_quit.

1985-05-12  Richard M. Stallman  (rms at mit-prep)

		scroll up all the lines that fit below bp.
	xdisp.c: introduce num_contin, to display tabs right in contin. lines
	doc.c: define substitute-command-keys, using crl@purdue's code.

	editfns.c: Put in code for & in fullname,
		under AMPERSAND_FULL_NAME flag.
	lisp.h: Install NO_UNION_TYPE flag in lisp.h.
		This means XMARKBIT can no longer be on left side of =.
		New macros XMARK and XUNMARK and XSETMARKBIT are used
		instead.
	alloc.c, marker.c: use XMARK, XUNMARK, XSETMARKBIT where needed.
	TrmTERM.c: Ignore `xs' termcap flag.
		Always use the SEstr on sg >= 0 terminals.
	minibuf.c: Don't allow entry to minibuffer
		while minibuffer is selected.
