But even the standard library breaks this rule on occasion.  e.g.,
/usr/lib/python2.7/urllib.py:1095 (I remember seeing others, but this is
the first example I was able to find quickly).

Personally, I try my best to keep all lines at 80 character max (80 +
newline, not 79).  In addition to liking my 84-character-width gvim windows
(to allow a little leeway) side-by-side for code references, I'm definitely
not above printing out some code to lay it out on a desk---that's not
something you can do on-screen without a wall of monitors in front of you.

The only time I regularly break my rule is for regular expressions (at some
point I may embrace re.X to allow me to break those up, too).

All the best,
Jason
