Fixes in 1991/ant/README.md

Browse Source 
Mostly formatting fixes but one spelling fix that I feel almost guilty
about.

Though programme is correct in most cases (except US English but the
author is from Canada) with computers it's actually program. It just
seems better to have this correct if I'm going to go through and look
for typos. Besides this is a programming contest so it makes sense that
it should be correct. Easy mistake to make but should it be fixed?
Maybe, maybe not but I chose to anyway.

Text files consists of lines of printable text or tab characters.
A line can be of arbitrary length and is delimited by either a
newline or the end of file. Carriage return is mapped to newline
on input and ignored on output. Tab stops are every eight columns.
Non-printable characters may have unpredictable results depending
on the implementation of CURSES.

### ABOUT THIS ENTRY:
The BUF size should be set at compile time to 32767. This value
was used because the Sozobon C compiler for the Atari ST has 16
bit ints and a limit on the size of arrays & structures of 32k.
Also the WatCom C compiler for the PC also has 16 bits ints. On
machines that have 32 bit ints (most unix boxes), a larger value
for BUF could be used.

It is recommend that compact memory model be used on PC class
machines. Small memory model may work too provided BUF is not
too large.

The character constants '\b', '\f', '\n', '\r', '\t' are used
in order to provide more portable code, since the compiler should
handle the translation of them into the native character set.
Note that '\f' (formfeed) was used to exit insert mode because
K&R C had no escape constant for the escape-key.

My goals for this project were to learn and experiment with the
Buffer Gap Scheme [Fin80][net90], write a useful and *portable*
programme, and meet the requirements of the IOCCC. I initially
planned to have a mini CURSES built-in like the IOCCC Tetris entry
program, and meet the requirements of the IOCCC. I initially
planned to have a mini `curses` built-in like the IOCCC Tetris entry
from a previous year, however this was not as portable as using a
CURSES library with TERMINFO/TERMCAP support.

I plan to post followups such as unobfuscated versions and bugs
fixes to comp.editors. Reposts of the editor.101, gap.doc, and
editor.102 can be found in the same group every so often.
