Reported by the clojure group by James Reeves:
„Does anyone else suffer from occassional incorrect indentations in VimClojure? It looks like VimClojure is preferring the indentation layer of a previous set of  over the current set of (). For example:
(defn foo [x] (+ x 1)) }}}
When I hit enter after the second "x", the 1 is indented a long way to the right. It seems to be getting it's indentation level from the argument vector, instead of from the current parentheses.
Here's another example:
(f something-very-long (g x y)) }}}
Is this just me, or does anyone else have this issue?“
James tracked this down to a rebinding on of the w command. VC executes a „normal w“ triggering the bug. The solution for the issue is to use „normal! w“ to avoid triggering eventually defined mappings.
Yokoten: go through the whole script to fix any invokation of a command which might trigger a mapping.
Why did it slip? I was well aware of „normal!“, but I didn't expect anyone to change the binding of w.
Prevent re-occurrence: For the future use only „normal!“ and check also other commands, whether mappings might get triggered.
Thanks to James Reeves for tracking this down!
