Subject: [PATCH 1/3] branch: streamline "attr_only" handling in validate_new_branchname()
Date: Fri, 13 Oct 2017 14:11:30 +0900	[thread overview]
Message-ID: <20171013051132.3973-2-gitster@pobox.com> (raw)
In-Reply-To: <20171013051132.3973-1-gitster@pobox.com>

The function takes a parameter "attr_only" (which is a name that is
hard to reason about, which will be corrected soon) and skips some
checks when it is set.  Reorganize the conditionals to make it move
obvious that some checks are never made when this parameter is set.
