Subject: [PATCH v3 1/8] remote.c: add braces in anticipation of a follow-up change
Date: Fri, 26 Oct 2018 23:07:34 +0000	[thread overview]
Message-ID: <20181026230741.23321-2-avarab@gmail.com> (raw)
In-Reply-To: <20181026192734.9609-1-avarab@gmail.com>

The CodingGuidelines say "When there are multiple arms to a
conditional and some of them require braces, enclose even a single
line block in braces for consistency.". Fix the code in
match_explicit() to conform.

While I'm at it change the if/else if/else in guess_ref() to use
braces. This is not currently needed, but a follow-up change will add
a new multi-line condition to that logic.
