only 29 commits to search from.  You can also git bisect on a particular
file, if needed.  But my guess is commit 95c948b06a, given the changelog
line:

    (process_file, du_files): Rewrite to use fts.

which 'git describe' puts after 5.0.91 but before 5.1.0.  I think your
guess was right. (And I spent more time on this email than I did on
searching git - such a change from the CVS days, where I have no idea
how long it would have taken to do the same sort of search for a culprit).
