Re: _expand doesn't do brace expansion?

Let me preface this by saying:  Don't feel obligated to do anything about
this at all; I'm just trying to make helpful suggestions.

} With `a{b,c}<TAB>' the completion code would have to generate the
} matches for `ab' and `ac', then built the intersection to get the
} suffixes (and prefixes if there's a suffix, i.e. the middle-strings)
} which are in both sets (in all n sets, actually).

Forget the intersection; complete the union.  With braces, it doesn't
matter if some of the results e.g. don't exist as files.

Usually I'm typing something like

	ln -s /usr{/local,}bin/blahblahblah

and what I want is to complete along *either* path, not along *both*,
because the thing I'm trying to complete only exists in one of them.

} combined with arbitrarily complicated match specs. Frightening.

There at least I think you'd be justified to consider anything inside a
closed pair of braces in the prefix to be ineligible for comparison to
match specs -- essentially, ineligible for anything that would insert
characters anywhere other than at the cursor.

Quite probably.
