Subject: [PATCH 18/20] abbrev parsing: use braces on multiple conditional arms

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Fri, 8 Jun 2018 22:41:34 +0000

Adjust this code that'll be modified in a subsequent change to have
more than one line per branch to use braces per the CodingGuidelines,
this makes the later change easier to understand.
