I think it is conceptually simpler on the show_reference side to
allow (filter.pattern == NULL) and say:

	if (!filter->pattern || !fnmatch(filter->pattern, refname, 0)) {
        	... show that ref ...
	}

It is not such a big deal now you do not do newpattern
allocation anymore, so I'll apply the patch as is.
