This would require:
1) rewrite all the error messages
2) provide a wrapper function and use it everywhere there is an error
both solutions are not very nice, also I think they're overkill, the
user should read the man page when he doesn't know nothing about the
Another way better solution would be to use some form of automatic
completion to immediately figure out which are the valid options (I
started to write sometime ago the completions for fish, if you're
interested I can post them here).
