This looks obviously correct, but two things that made me wonder
briefly were:
1. is reprepare_packed_git() a bit too heavy-weight, if the only
thing we are addressing is the loose-object cache going stale?
2. is there a way to cleanly avoid the three-line duplicate?
My tentative answers are (1) even if it is, but get_short_oid() is
already heavy-weight enough; it won't be worth restructuring the
code to make it possible to clear only the loose-object cache, and
(2) a loop that runs twice when the first result is MISSING_OBJECT
and otherwise leaves after once would need an extra variable, its
iniialization, check and increment, which is more than what we might
save with such a restructuring, so it won't be worth pursuing.
But others may have better ideas, as always ;-)
