I wonder if we can use "sort -u" here and drop uniq. It isn't quite the 
same as it will remove entries that are equal according to the current 
locale but I don't think that should matter.

With that tweak this looks good. If there are no glob characters then 
"git for-each-ref" does a prefix match so strictly speaking you don't 
need the '**' but I don't think it matters in practice. I had one 
thought below but if you don't feel like spending more that on this I 
think what you have here is fine.

The filtering is O(number of remote refs * number of remotes). If we 
could sort the list of remotes and remote refs in the same order then we 
can reduce this to O(number of remote refs + number of remotes) by doing 
(in pseudo code)

     for ($ref in $remote_refs) {
	while (!starts_with($ref, "refs/remotes/$remote[$i]"))
		$i++;
	if (starts_with($ref, "refs/remotes/$remote[$i]/$cur_)
		print $ref;
     }

I think we can get "git for-each-ref --sort=-refname" and "sort -r" to 
agree on a sorting order by setting LC_COLLATE=C, otherwise "sort" will 
sort according the the current locale whereas git sorts by bytes.

Best Wishes

Phillip
