The problem is that as your branch diverges from what you *actually* want to commit, it becomes exponentially more complicated to figure out what you *do* want to commit.

Note that if you're planning to share your git project with other people anyway, then you have an additional problem: you're using git svn rebase, which is almost useless for sharing with other people (other than through svn, of course), for the same reason any git rebase is.

One option you have is to maintain two branches:

1. (git-svn) The git-svn trunk, which contains only stuff you want upstream

2. (master) Your live branch, which contains everything from (1) plus
your local customizations.

When you want to fetch from svn, you do this:

  git checkout master
  git svn fetch git-svn
  git merge git-svn

When you want to push to svn, you do this:

  git checkout git-svn
  git merge --squash --no-commit master
    (now undo your local customizations)
  git commit
  git svn dcommit
  git checkout master
  git merge git-svn

Note that master never gets rebased, only merged. If you can write a simple script for "undo your local customizations" - such as reverting a particular commit, for example - then you can put the above in a shell script and it should work fine most of the time.

Good luck.
