Why can't I:

( cd master-repo && git-svn-mirror )

git clone --local -b <branch> master-repo branch-wc
cd branch-wc
(do work)
git commit  (do I need to do this? -- I'm guessing I do)
git svn dcommit

What does git-svn-mirror do specially, beyond what a git svn fetch would
do in a "pull-only" repo?  I'm asking because I do not know exactly how
the existing git-svn repo is pulled/updated at work (yes, there is on). 
So *theoretically* I could clone --mirror that one similarly to how I'd
work with the gnucash tree, but I'd only do that if I could dcommit back
without causing issues.  And honestly I don't know how to test that
without actually doing a commit.
