No, thank you!

C is a symbolic language, not a text language. Encouraging newbies to declare

	int iterator;

instead of

	int i;

does the language a disservice.

It's true, nobody uses a TTY33 anymore. Those of us who have done so
understand how "{" is preferable to "BEGIN" and why tabs are better than
multiple spaces. A narrow "terminal" requires less neck and mouse movement.
Any width limit is arbitrary, so to the extent anyone might care, I advocate
80 forever.
