Subject: [PATCHv2 5/6] diff: properly error out when combining multiple pickaxe options
Date: Thu, 4 Jan 2018 14:50:43 -0800 [thread overview]
Message-ID: <20180104225044.191220-6-sbeller@google.com> (raw)
In-Reply-To: <20180104225044.191220-1-sbeller@google.com>
In f506b8e8b5 (git log/diff: add -G<regexp> that greps in the patch text,
2010-08-23) we were hesitant to check if the user requests both -S and
-G at the same time. Now that the pickaxe family also offers --find-object,
which looks slightly more different than the former two, let's add a check
that those are not used at the same time.
