Subject: git-send-email: avoid uninitialized variable warning.
X-Git-Tag: v1.4.3-rc2~13
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bc108f63dad7a5f6d95418cb78a587f5f570eae6;p=git.git

git-send-email: avoid uninitialized variable warning.

The code took length of $reply_to when it was not even defined,
causing -w to warn.
