Thanks, I knew this and intended to change it to OPT_BOOL but forgot.
(The OPT_BOOLEAN was inherited from check-attr.c and check-ignore.c
which I used as templates for check-mailmap.c.)

Indeed, it's not ideal. I chose "contact to stdout" for consistency
with other callers, not because of a fondness for it.

  % git grep maybe_flush_or_die
  builtin/blame.c: maybe_flush_or_die(stdout, "stdout");
  builtin/check-attr.c: maybe_flush_or_die(stdout, "attribute to stdout");
  builtin/check-attr.c: maybe_flush_or_die(stdout, "attribute to stdout");
  builtin/check-ignore.c: maybe_flush_or_die(stdout, "check-ignore to stdout");
  builtin/check-ignore.c: maybe_flush_or_die(stdout, "ignore to stdout");
  builtin/hash-object.c: maybe_flush_or_die(stdout, "hash to stdout");
  builtin/rev-list.c: maybe_flush_or_die(stdout, "stdout");
  log-tree.c: maybe_flush_or_die(stdout, "stdout");

They seem pretty evenly split between just "stdout" and "foo to
stdout". (I actually prefer plain "stdout" and will happily change it
to that.)
