I have just noticed that oper_select_candidate()'s first try at
resolving unknown-type inputs (parse_oper.c lines 372-410 in current
sources) is entirely redundant, because the case it is looking for
has already been tried by oper_exact().  I propose removing that
code, to make it more like func_select_candidate.  Have I missed
anything?
