Subject: Authenticate only once in git-send-email
X-Git-Tag: v1.5.4-rc0~164
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5f5b611805ed60a303ccbc07ebd9a5bac2dabb92;p=git.git

Authenticate only once in git-send-email

When using git-send-email with SMTP authentication sending a patch series
would redundantly authenticate multiple times, once for each patch. In
the worst case, this would actually prevent the series from being sent
because the server would reply with a "5.5.0 Already Authenticated"
status code which would derail the process.

This commit teaches git-send-email to authenticate once and only once at
the beginning of the series.
