Subject: git-send-email: add rfc2047 quoting for "=?"
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ce1459f740a591c63697ff6ff3c106123630539c;p=git.git

git-send-email: add rfc2047 quoting for "=?"

For raw subjects rfc2047 quoting is needed not only for non-ASCII characters,
but also for any possible rfc2047 in it.
