But it's *Berkeley* that had the smart stdio in the first place! I know
that I ran into this on 2.something at Berkeley in 1980 and thought it
was way-cool. When and why was it removed, or did it just not get migrated
to 4BSD?

And providing another putc won't help 'printf("%s-> ", mode);' and other
prompt-like stuff. Nor will it help the overall speed problem.

Sideways compatibility?
