Since b92891f9783 (parseopt: add PARSE_OPT_NO_INTERNAL_HELP,
2009-03-08) parse_options() has handled "-h" unless told not to, so
when show-ref was migrated to parse_options() in
69932bc6117 (show-ref: migrate to parse-options, 2009-06-20) the
custom "-h" handling that was retained did nothing.

The option was then hidden in e62b3935056 (Show usage string for 'git
show-ref -h', 2009-11-09), but that OPT_BOOLEAN didn't do
anything. Let's just remove this dead code.

While this is a fine no-op, I am not sure this "fixes" complaint
in Ignacy's report.  "git show-ref -h" would (and should) show the
short-help, no?

It would, but -h is not a no-op without this patch.  The option is
equivalent to --heads as long as it's not the only argument.  E.g. it
has an effect in "git show-ref -h HEA." or "git show-ref -hh".

Ah, so this actively breaks the command?  Yeah, thanks---I smelled
something fishy in the change.
