[RFC PATCH 0/3] Submodule filtering for filter-branch

Jeffrey Phillips Freeman aka tty1 asked on IRC about a way to fix the super-project after rewriting submodules. This quick series provides some extra tricks in the filter-branch toolbox that can be plumbed together to achieve this (see the last commit's message), and should hopefully be general enough to be of other use too.

Comes without docs and tests at this point, hence RFC. It's also only lightly tested, but since Jeffrey has a use-case, I'll leave it up to him to bend it a bit and see if anything breaks.

Thomas Rast (3):
  filter-branch: optionally dump all mappings at the end
  filter-branch: optionally load existing mappings prior to filtering
  filter-branch: support --submodule-filter
