Changing to the empty marco removes the side effects in the arguments (such as len++, for example),
which may silently break existing code -- so I think it's not a good idea.  If the idea to use the empty
arguments was not to implicitly document them (because the API was slated for removal, IIRC), then
naming them just with "arg1", "arg2" (rather than leaving empty altogether) should help better, IMO.
