- remove bashism - simplify some git-related code - there is only one sane time format. - vastly improve git_url() to print the correct remote url and "nearest" branch - add "-dirty" to local revisions if there are uncommitted changes - indicate in local revisions how many git-only commits were done since branching from upstream svn - fix svn_revision() fallback to svn info and remove git-svn - print leading r in script instead of hardcode it in the makefile; no more "0.9.7-runknown"
