| Before this commit, if the value didn't begin with a dollar sign,
_zsh_highlight_main_highlighter__try_expand_parameter() would return 1
by accident.¹  Tweak the input validation to make this behaviour
explicit.  No functional change.
¹ Specifically, it would return 1 because ${parameter_name}'s value
would be the empty string and ${parameter_name_pattern} wouldn't match
that. | ||
