Re: BR 1582430: Allow numbers with leading + or - for %ifnum

Hehe, funny that you mention that -- I did add %IFTOK0
and %IFTOK1 in NASM64: check for exactly zero or one
tokens.  

But back to %IFNUM.

Don't get me wrong -- there are times when accepting a
sign as part of a number is the desired behavior. But the
only one who can tell, is the user.

I kinda hate to suggest it... but perhaps this one of those
few times were a user-selectable option is needed?

I already had to deal with that for two things in NASM64:
expand certain tokens before/after listing them, as well
as looking up context-local definitions in outer contexts.
As a result, I added %OPTION [-|+]EXPAND, as well as
%OPTION [-|+]LOOKUP -- perhaps %IFNUM requires a
new %OPTION [-|+]SIGNED or such...?

I think the combination of %iftoken and %ifnum should be
able to do what 
anyone needs.  I'd be open to adding %ifempty as well.
