[PATCH 0/5] commit-graph: parse_options() cleanup

A trivial cleanup series as a follow-up to my comments in https://lore.kernel.org/git/87r1lhb6z7.fsf@evledraar.gmail.com/

Ævar Arnfjörð Bjarmason (5):
  commit-graph: define common usage with a macro
  commit-graph: remove redundant handling of -h
  commit-graph: use parse_options_concat()
  commit-graph: refactor dispatch loop for style
  commit-graph: show usage on "commit-graph [write|verify] garbage"
