[PATCH 15/20] parse-options-cb.c: use braces on multiple conditional arms

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

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.
