Count me in the "80-chars is ante-deluvian gunk" camp

Thats a strange self-contradiction.  I wrote this:
 http://blog.languager.org/2012/10/layout-imperative-in-functional.html
to make the case against PEP8 style line length strictures.
Which has the SAME code formatted in two styles:

--  < 80 cols, 48 lines
--  115 cols 37 lines

Clearly the 115 cols is MORE fittable in a page than the 80 cols
[Though my argument for that is based on other structural/semantic principles]

Should mention an irony here though:
When I first wrote it, the examples were inline and blogger was breaking the lines randomly completely invalidating my point.
IIRC blogger was breaking at 68 cols -- invalidating the 80 cols from the other side.
Clearly 80 cols is more portable than longer.
However if we literally implement the view that different people use different
technologies -- AND WE SHOULD SUPPORT THEM ALL -- then notepad becomes the
ineluctable gold standard.
