Given a file with:
(define archive-id "$Format:%ct|%h|a$")
and an export-subst attribute, the "%h" results in an full 40-digit
object name instead of the expected 7-digit one.
The export-subst feature requests unabbreviated object names because
that is the low-level default. The effect was not observable until
v1.7.1.1~17^2~3 (2010-05-03), which taught log --format=%h to respect
the --abbrev option.

I carried over the tested-by; I hope that’s okay. Well, I’ve tested
the new patch myself, at least. :)
