Subject: send-email: do not muck with initial-reply-to when unset.
X-Git-Tag: v1.5.4-rc0~21
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ace9c2a9dd7c9e54194998fc6b7c677dbb7d0902;p=git.git

send-email: do not muck with initial-reply-to when unset.

When not prompting, initial_reply_to can be left unset.  Do not try to
sanitize it and get useless warning.
