Subject: update-index: allow "-h" to also display options
X-Git-Tag: v1.8.1.6~10^2

update-index: allow "-h" to also display options

Even though "git update-index" was updated to use parse-options
infrastracture some time ago to make it possible to show list of
options with usage_with_options(), "git update-index -h" only shows
the usage.  Detect this case and call usage_with_options() to show
the list of options as well.
