I think that would be ok. Though it would also be nice to remove
some|all entries from the list being provided to the user. Also, it
would be nice to provide help text for items. I don't think that can be
currently done with the fake-* styles.
Also, since I was limiting the scope to _arguments, it would be possible
to provide alternative action function or state.

Yes, something like that could be done for this specific case. Playing
with the completion generation stuff, I find that I want to use code
from the "state" actions of existing completion functions a lot. It's
not possible. It seems that unless a state is very specific to a
particular command, we should recommend people create new action
functions over action states.

This is the sort of feedback I was interested in. Though, it's not
clear to me why a completion function is better. I've sort of thought
that making a completer that got much of it's information via styles
might be easy to create.

I believe _regex_arguments is more for complex groups of flags/arguments
not for dealing with completion within a string, but could be wrong.
