git-svn: teach find-rev to find near matches
When a single SVN repository is split into multiple Git repositories many SVN revisions will exist in only one of the Git repositories created. For some projects the only way to build a working artifact is to check out corresponding versions of various repositories, with no indication of what those are in the Git world - in the SVN world the revision numbers are sufficient. By adding "--before" to "git-svn find-rev" we can say "tell me what this repository looked like when that other repository looked like this": git svn find-rev --before \ r$(git --git-dir=/over/there.git svn find-rev HEAD) Signed-off-by: John Keeping <john@keeping.me.uk> Signed-off-by: Eric Wong <normalperson@yhbt.net>

You should consider using 'dcommit' instead of this command.
