Subject: [PATCH 16/20] abbrev: unify the handling of non-numeric values
Date: Fri,  8 Jun 2018 22:41:32 +0000	[thread overview]
Message-ID: <20180608224136.20220-17-avarab@gmail.com> (raw)
In-Reply-To: <20180608224136.20220-1-avarab@gmail.com>

Unify how --abbrev=XYZ and core.abbrev=XYZ is handled. 2/4 parsers for
these values would just let these invalid values pass, treating them
as though "0" was provided, which due to other inconsistent fallback
logic (soon to be fixed) would be treated as providing MINIMUM_ABBREV.
