SVN mergeinfo is not representable in Git.  It records which changesets
have been copied over from one branch to another.  Git doesn't do
changesets *at all*: it just stores tree contents, and it records one or
multiple parents for every commit.  That isn't actually derivable from
the SVN info.  You can guess, and you can guess wrong.

Branch merges do not mesh well with our commit policies, fwiw:
everything should normally be posted for public review on the mailing
lists.  This does not really work for commits that have been set in
stone months before.
