So let's try this one. The first two do not depend on
--simplify-merges.
1/3 is new, and extends the --subdirectory-filter test to prove the
existence of the bug in current filter-branch. I hope it helps
explain the issue.
2/3 is the same as before[*] modulo changing the test to expect
success again.
The third one does depend on --simplify-merges.
3/3 introduces --simplify-merges, which improves the history that
results from --subdirectory-filter. It has absolutely nothing to do
with 2/3, except that it touches the same area of code. (You could
s/rev-list/rev-list --simplify-merges/ in master:git-filter-branch.sh,
and get the improved history without the bugfix.)
Sorry that I dispersed the patches and v2s randomly across the thread.
