So it sounds like this bug was introduced by the upstream 7814fbe
commit, although I've not explicitly verified that.  There are currently
some related conversations going on at the Git mailing list[0], which
sound like they may produce something that improves things here.

In any case, I'll add this to my tracking list and get it reported
upstream if appropriate.
