parse-options: never suppress arghelp if LITERAL_ARGHELP is set
The PARSE_OPT_LITERAL_ARGHELP flag allows a program to override the
standard "<argument> for mandatory, [argument] for optional" markup in
its help message. Extend it to override the usual "no text for
disallowed", too (for the PARSE_OPT_NOARG | PARSE_OPT_LITERAL_ARGHELP
case, which was previously meaningless), to be more intuitive.
The motivation is to allow update-index to correctly advertise
--cacheinfo <mode> <object> <path>
add the specified entry to the index
while abusing PARSE_OPT_NOARG to disallow the "sticked form"
--cacheinfo=<mode> <object> <path>
