The problem with git and svn integration is that you have to rebase your
git branch onto the svn branch to merge your changes back to svn. You
thereby loose the true history of your git branch. And you also make it
difficult for anyone to track your git branch because you've rebased
(rewritten history). Thus, use of git-svn doesn't really make code
sharing much easier -- in general, there still has to be svn in there.
Furthermore, because there is no birectional one-to-one map between git
and svn branches, in practice only one svn branch, probably the trunk,
can be used within a git system.
