Subject: [PATCH v2 10/12] get_short_oid / peel_onion: ^{commit} should be commit, not committish
Date: Tue,  1 May 2018 12:06:49 +0000	[thread overview]
Message-ID: <20180501120651.15886-11-avarab@gmail.com> (raw)
In-Reply-To: <20180501120651.15886-1-avarab@gmail.com>
In-Reply-To: <20180430220734.30133-1-avarab@gmail.com>

Change the ^{commit} syntax to mean just commits instead of committish
for the purpose of disambiguation. Before this e8f2^{commit} would
show the v2.17.0 tag as a disambiguation candidate, but now it'll just
show ambiguous commits:

    $ git rev-parse e8f2^{commit}
    error: short SHA1 e8f2 is ambiguous
    hint: The candidates are:
    hint:   e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name
    hint:   e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src
    hint:   e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries
    [...]
