[PATCH 1/3] show-ref: remove unused custom handling of -h

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

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.
