Subject: [PATCH v2 1/3] am: add --show-current-patch
Date: Wed, 31 Jan 2018 16:30:48 +0700 [thread overview]
Message-ID: <20180131093051.15525-2-pclouds@gmail.com> (raw)
In-Reply-To: <20180131093051.15525-1-pclouds@gmail.com>
Pointing the user to $GIT_DIR/rebase-apply may encourage them to mess
around in there, which is not a good thing. With this, the user does
not have to keep the path around somewhere (because after a couple of
commands, the path may be out of scrollback buffer) when they need to
look at the patch.
