cherry-pick: detect bogus arguments to --mainline
The cherry-pick and revert commands use OPT_INTEGER() to parse --mainline. The stock parser is smart enough to reject non-numeric nonsense, but it doesn't know that parent counting starts at 1. Worse, the value "0" is indistinguishable from the unset case, so a user who assumes the counting is 0-based will get a confusing message: $ git cherry-pick -m 0 $merge error: commit ... is a merge but no -m option was given. Let's use a custom callback that enforces our range. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
