ifmatchbug is fixedid! grin

Edited: I dont reckon there ever was an $iif($ifmatch, ...) bug, just an $iif($isid, ...) bug.
The following code works on versions all the way back to 5.81 (2000-Nov-9).

//if (abc) echo -a > $ifmatch $iif($ifmatch,$ifmatch y,n)
> abc abc y

Well. At least I won lunch.
Good philosophy, see good in bad, I like!
