Quite some items in the 'Limits' sections aren't actual limitations so it seems appropriate to just use a more neutral term.

25 rows by 24 columns are used. 24 columns is
also the width that is fully displayed on a real
C1P on the monitor. conio now matches that now.

If kbhit() detects that a key is pressed, it fetches and
buffers the character. If cgetc() detects a buffered character,
this one is returned instead of fetching one with the PROM
routine.
