Heavens.   This conversation is /sooo/ 1985.

Here's my problem with the 80 character convention:

1. I'm also in favor of long identifier names.
2. Line breaks among the arguments to a function call should not be
   randomly placed.


Thus, I'm often left with a choice between something like:


  frob (foomodule_munge (zap_param, x), bazmodule_grunge, expert_knobs () + 10, 
0, 0)

and something like:

  frob(foomodule_munge (zap_param, x),
       bazmodule_grunge,
       expert_knobs () + 10,
       0, 0)

The former, combined with wide windows, let's me get (in this case) 
4x as many statements on the screen as otherwise!

I'm all for the 80-column restriction (actually a smaller limit) on
the parameter declaration part of a function definition (because I
expect that to be cut and pasted into documentation).  I'm in favor of
the 80-col restriction on the commentary text that comprises
documentation.   But for all those long function call statements: the
utility of wide windows seems dominant to me.

A roughly full-screen Emacs window should show must of the code that I
format in, at least roughly, the intended way.

In an emergency, deprived of anything but some ancient dec terminals,
I intend to print out pages of my code on a wide lineprinter and then
muddle through editting it on a VT-52 but, aside from that, I don't
seem to be suffering from the lack of interactive wide displays and
neither does nearly anyone else.  So why not take advantage of them?
