I made this change.

The resulting name, if any, is put into a symbol by symbol_set_names.
(I didn't change this area, just made it so the existing code could be
factored into per-language methods.)

So, it should be whatever is appropriate for a symbol.

I think this area is still a bit messy.  IIRC there are some weird
demangling differences between psymbols and full symbols, and there is
still a hack for Java in symbol_set_names.
