[PATCH 0/6] Minor fsmonitor bugfixes, use with `git diff`

[Alex Vandiver <alexmv@xxxxxxxxxxx>]

This cleans up some mistakes I introduced in my previous series, and
switches `git diff` to use the fsmonitor data.

I've noticed that `git checkout HEAD` drops the fsmonitor data, which
surprises me -- the following patch "fixes" that but broke tests, so
there's something I clearly don't understand yet going on here:
