Subject: format-patch: Squelch 'fatal: Not a range." error
X-Git-Tag: v1.7.0.4~10
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=657ab61efa918f46f1b412613643d1a1bbed2194;p=git.git

format-patch: Squelch 'fatal: Not a range." error

Don't output an error on `git format-patch --ignore-if-in-upstream HEAD`.
This matches the behavior of `git format-patch HEAD`.
