Just did that in the before-filtering repository, and "gitk HEAD --
WRITING" doesn't have any branches after the simplification but it
does go back to the first commit in the repository creating WRITING
(presumably simplifying out several branches that didn't affect
WRITING), whereas the filtered repository starts on the commit
immediately after the first merge you encounter walking backwards in
time. I was prepared for the branch structure to possibly simplify
whilst keeping all the commits that change that directory, but was a
bit surprised it stopped before the first merge.

<in original>
$ git log HEAD -- WRITING | wc -l
   2033

<in filtered repo>
$ git log | wc -l
329

So it's definitely creating a smaller repo than git log filtering. If
you would be interested in looking at the actual repo (about 17M) let
me know and I'll send you tarball details via personal mail.

Anyway, many thanks for the insight and assistance,
