Subject: [PATCH v2 0/4] filter-branch: support for incremental update + fix for ancient tag format

From: Ian Campbell <[email-masked]>

This is the second version of my patches to add incremental support to
git-filter-branch. Since the last time I have:
 * addressed the review feedback (see changelog embedded in final
   patch)
 * switched to using the (newly introduced) `--allow-missing-tagger`
   option to `git mktag` to allow early Linux kernel tags to be
   rewritten
 * split out some of the preparatory changes to make the final patch
   easier to read.

I've force pushed to [1] where Travis seems happy and have set off the
process of re-rewriting the devicetree tree from scratch (a multi-day
affair) to validate (it's looking good).

Ian.
