as it happens currently if the user sets llayer incorrectly (by not
setting it at all).

easier said than done; the parser can't know before hand what the answer
to another option will be. but it is possible to give it no default and
add to the llayer's option description that it will use the layer= answer
if not given. While possible, I'm still not sure if it's advisable. (shrug)
