On a "crt", when erasing a character in an input line the 4.3BSD 'more'
program winds up writing a NUL after each backspace-space-backspace sequence.
This ordinarily isn't a problem, except on terminals that
display a NUL as a visible character (my terminal prints out
all control characters that aren't part of an escape sequence
as visible characters). Here's a suggested fix. This also applies
to the 'more' on SunOS 4.0.
