With my current setup tab completion of a word with curly braces in it
(e.g. foo{bar,biz}) Zsh expands it. For example:
% diff ./{old,new}/obnoxiously_long_f<TAB>
% diff ./old/obnoxiously_long_f ./new/obnoxiously_long_f
I'd really like to have the shell avoid expansion and instead look for
possible completions using the union of the file names under all
expansions. For example:
% diff ./{old,new}/obnoxiously_long_f<TAB>
% diff ./{old,new}/obnoxiously_long_file_name.
obnoxiously_long_file_name.c obnoxiously_long_file_name.h
where obnoxiously_long_file_name.c and obnoxiously_long_file_name.h
exist in both old and new. I imagine it wouldn't be too difficult to
write a completion function for this and I already have the completer
set up to favor completion over expansion. Is this completion function
already implemented?

Hmm ... with my setup it does not complete anything at all.
Could you show "zstyle -L"?

The first line is the one that enables expansion. Notice that
expansion is only tried after all other methods have failed.

This is unfortunately quite difficult. Completion is really designed
to resolve one argument to one matching string; what you're in effect
asking for here is to simultaneously complete two arguments at once.
This doesn't even work with glob completion; e.g. if instead you try
% diff ./(old|new)/ob<TAB>
or even
% diff ./*/ob<TAB>
it'll first insist that you resolve the pattern part down to one or
the other of old or new before proceeding to complete path tails.
You can't do this by adding another completer like _expand or _match.
Those are invoked at too high a level. To make this work you'd have
to hijack file completion somewhere down in the guts of _path_files,
and pass "{old,new}' directly to compadd -Q so the brace expression
(or pattern in the glob case) becomes part of the completion result;
and *then* when completing the later portions of the path I believe
you'd need to do the comparisons yourself to assure that the full
result really does match all branches of the brace expression.
However, you might almost be able to get what you want from the
_expand completer by simply appending a "*" to the argument before
you complete, and then accept the all-expansions group of matches.
E.g.:
% diff ./{old,new}/obnoxiously_long_f*<TAB>
should offer something like (among other stuff):
Completing all expansions
./old/obnoxiously_long_file_name.c ./new/obnoxiously_long_file_name.c
and it wouldn't be so difficult to whip up something to automatically
insert that "*" before attempting the expansion.
