Yes.

Do we want 1 or 128 just like die()?

Given that I see this behaviour:
$ git rev-parse da/rev-parse-verify-quiet@{1}
2892dfeec3f98f7e65a2746d271471d2c3c4af57
$ git rev-parse da/rev-parse-verify-quiet@{10}
fatal: Log for 'da/rev-parse-verify-quiet' only has 4 entries
and I do not see a change in this patch to touch "only has %d
entries" (found in sha1_name.c), I have to suspect that this change
is not sufficient to say "rev-parse --quiet will now be quiet".
$ git rev-parse --quiet --verify da/rev-parse-verify-quiet@{10.years.ago}
may want to return the oldest-known value as it has always done
without giving a warning.
There probably are other cases that relate to reflogs, e.g.
$ git rev-parse --quiet --verify @{-99999}
to ask the tip of the branch you were on 99999 "git checkout"s ago.
I think the last one does not have to be in the same commit as this
fix for "empty" and "you do not have that many" cases, though.
Thanks.
