[PATCH] git filter-branch: Process commits in --date-order

[Peter Rosin <peda@lysator.liu.se>]

When converting an svn repository to git, I am filtering the commits
using --msg-filter. During this conversion I want to use the
.git-rewrite/map data to fill in references to other commits. In the
svn repo, there is a commit message e.g. "Cherry-pick r207", and I
want to append "r207 = <commit>" to the git commit message, as r207
no longer means very much. This works fine when the git commit
corresponding to r207 has been filtered before the current commit, and
is present in the map. When filtering in --topo-order, this is not
always the case, making it impossible to look up the git commit.
