Subject: split directories into branches
Message-ID: <CAH_OBieCcx0_=vuZgoJ8GrZhhReEAhnjrz2pQwbwGgPFww4JmQ@mail.gmail.com>

I've got a chef cookbook repo where everyone started developing
cookbooks in a single dev branch (not project specific). Minus a few
edge cases, it should be fairly simple to split this up into feature
branches based on /cookbooks/<feature>.

I tried:
$ git filter-branch --subdirectory-filter cookbooks/<feature>-- <feature>
And
$ git subtree split --prefix cookbooks/<feature> -b <feature>

Which both seem to do the same thing (haven't looked at the subtree
bash - guessing it does exactly the filter-branch). The issue is that
it removes the directory tree (so obviously merges wouldn't work). I'm
thinking some type of filter-branch --index-filter with a cherry pick
(or similar) should work...?
