Subject: [PATCH 2/3] range-diff: handle commit ranges other than A..B
Date: Thu, 21 Jan 2021 22:20:37 +0000 [thread overview]
Message-ID: <88c15617b4ba8ae3211b1a01861eb4165f3eda38.1611267638.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.841.git.1611267638.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
In the `SPECIFYING RANGES` section of gitrevisions[7], two ways are
described to specify commit ranges that `range-diff` does not yet
accept: "<commit>^!" and "<commit>^-<n>".
Let's accept them.
