color: Add tests for colorized diff and status output.

diff colorization: finish highlighting trailing whitespace

color: diff colorization This colorizes diff, qdiff, log -p, outgoing -p, incoming -p, and tip -p.

color: add --color switch --color works like GNU grep --color. --color=auto only colorizes output for non-dumb terminals that are TTYs.

mq: filter out empty commit messages in qfold

mq: drop copy sources removed during qfold (see issue1405)

inotify: do not complain that inotify is not running if autostart is False

inotify: close most file descriptors when autostarting Otherwise, operations that autostart while talking to an SSH repository prevent SSH stderr from closing normally. This causes hangs at the end of hg clone or hg pull -u.

hgweb: extend [paths] syntax to match repositories recursively (issue852) This feature somehow duplicates [collections] but it is simpler to use and has less issues under Windows where using absolute path as configuration file key is not supported. Suggested by Dirkjan Ochtman <dirkjan@ochtman.nl>

help: try topics before commands to avoid "diffs" showing help for diffstat
