Subject: git-format-patch: --stdout option.
X-Git-Tag: v0.99.9~187
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=655c7470e2ea7f25f22703b6654d7570e1567a39;p=git.git

git-format-patch: --stdout option.

This new flag generates the mbox formatted output to the standard
output, instead of saving them into a file per patch and implies --mbox.

It also fixes a corner case where the commit does not have *any* message.
