mq: do not call ui.username unless it is necessary After changeset c63c336ee2f7, ui.username will abort by default if no username is set. It is therefore wrong to call ui.username when a username was provided on the command line.

util: sort paths in walkrepos() (fixes test failures in test-hgwebdir)

hgweb: treat rev as raw-rev if user agent is hg

patchbomb: fix 'echo -en' bashism in test-patchbomb The echo command doesn't accept options in some shells. printf is required by the SUSv2 (Single UNIX Specification v2).

Issue919: add a standard extension to recreate hardlinks between repositories. Having to run a standalone Python script from the contrib dir is a nuisance. Also makes various improvements to locking, file discovery, etc. Should also update: http://www.selenic.com/mercurial/wiki/index.cgi/RecreateHardlinksBetweenRepositories

tests: glog with style and file parameter (issue1896)

graphlog: don't pass filectxs to the templater (issue1896)

keepalive: handle broken pipes gracefully during large POSTs

diff: add --inverse option Most of the time, one can reverse a diff by swapping the revisions passed with -r but it happens that if you use the global -R, and diff against the tip of the current repo, you can't swap the revisions. One use-case for that is reviewing changes from a bundle before unbundling. One could also pipe the output of `hg diff` to a command line filter that reverses the diff, but that would remove the benefit from color diffs. Therefore, having an option in `hg diff` to reverse a diff is a good thing. The option flag selection was tricky. GNU patch uses -R/--reverse but -R is already used as a global option and --reverse would make --rev ambiguous.

hgweb: keep original order from hgwebdir config files (issue1535)
