	Of course, you realize redefining putc will have no effect on printf...

Silly me! I *axually* believed the UNIX documentation! I quote from
man 3 printf:

... Characters generated by printf are printed by putc(3S).

Well, that may have been once true, and the effect is mostly the same.
Okay, so I picked a bad example. Lets go one level up. I could
redefine printf to remove all that floating point stuff I
don't want or need, and maybe add a few formats of my own (You hear
a faint cry of anguish (about portability) in the background).

THEN, I am free to redefine putc, perhaps to print unprintable
chars as ^X for control X, etc. In fact I did this to `more'.

	Thanx for setting me straight
