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.
