Subject: git-send-email: Add --threaded option
X-Git-Tag: v1.5.3-rc0~51
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e46f7a0e1c641cd80affd80516677f1e370cd72c;p=git.git

git-send-email: Add --threaded option

The --threaded option controls whether the In-Reply-To header will be set on
any emails sent. The current behavior is to always set this header, so this
option is most useful in its negated form, --no-threaded. This behavior can
also be controlled through the 'sendemail.threaded' config setting.
