This is a good idea, but... Here's my results from just running awk for
\t, \n, and \b:
$ awk 'BEGIN { print "a\tb" ; exit }';
a b
$ awk 'BEGIN { print "a\nb" ; exit }'
anb
$ awk 'BEGIN { print "a\bb" ; exit }'
abb

Strange. It looks like it's just ignoring the backslash in the case of
\n and \b.

I'm not looking for code review, but the
code is intended to replace the
tabs and backspaces with \t and \b respectively, but I haven't been able
to test it because I can't seem to make a backspace character appear in
input. In later unices, ^V followed by the backspace would work, but
that's not part of v7. Backspace itself is my erase character, so
anytime I just type it, it backspaces :).
awk 'BEGIN { print
"a\bc\td" ; exit }' | your-program
Enjoy,
Arnold
P.S. The exit is needed for V7 awk, IIRC, not modern ones.
