Well, I'm not immediately familiar with this code.  At first thought,
there might be some complexity because search_symbols takes a regexp,
but that's easily resolvable.  More importantly,
make_symbol_overload_list respects scope.  So no, the two are not
equivalent.

I found at least one more bug in overload_list_add_symbol (extraneous
realloc calls) while looking this over, though.  I also understand
where those loops came from, more or less; see make_completion_list. 
This function (and its comments) need some housecleaning.
