parse-options: PARSE_OPT_KEEP_UNKNOWN only applies to --options
The description of 'PARSE_OPT_KEEP_UNKNOWN' starts with "Keep unknown
arguments instead of erroring out". This is a bit misleading, as this
flag only applies to unknown --options, while non-option arguments are
kept even without this flag.
Update the description to clarify this, and rename the flag to
PARSE_OPTIONS_KEEP_UNKNOWN_OPT to make this obvious just by looking at
the flag name.
