  IMHO here is what git-svn should do. It should use the not-so-new
remotes mechanism, and have all the svn remotes branches under a remote
namespace, clean, simple, and also knowing which "upstream" svn "thing"
it's following.

  Then, when you just git checkout --track -b <branch> <svn-remote/foo>

  hack hack hack
  git commit
  hack hack hack
  git commit
  git merge <svn-remote/another-branch>
  hack hack hack
  git commit

  and then you just want to:

  git svn dcommit.

  Using the fact that <branch> tracks <svn-remote/foo> and that
<svn-remote/foo> is in fact the plain mirror of upstream's branch foo,
it should be able to know where to actually commit and wrt what it has
to make history clean.


  IMHO a git-$scm gateway just has to feed "remotes" branches, and
provide some plumbing commands (like dcommit) to be able to feed some
changes to the other $scm, with a workflow like this one:

  1. pull $scm into a shadow git repository
  2. import/merge $scm changes into your local branch
  3. make changes / merges whatever
  4. push $scm..<yourbranch> into $scm
  5. goto 1, so that you can "win" your changes from 4. back in the $scm
     local shadow repository.
