Pg_upgrade displays file names during copy and database names during dump/restore. Andrew Dunstan identified three bugs:
* long file names were being truncated to 60 _leading_ characters, which often do not change for long file names
* file names were truncated to 60 characters in log files
* carriage returns were being output to log files
This commit fixes these --- it prints 60 _trailing_ characters to the status display, and full path names without carriage returns to log files. It also suppresses status output to the log file unless verbose mode is used.
