I wasn't thinking about Emacs as one of these tools; rather:
* grep on the command line
* viewcvs diff screens on the web
* any other visual diff tool
* syncmail, the cvs checkin notifier which sends diffs as emails.
Emails wrap at 76 columns in most clients.
* KDevelop

stop thinking of text files ... rather 'source files' which are
higly sensitive to newlines.

80 is THE standard. Like Ian said anything else is being arbitrary
without good reason.

This is nothing to do with emacs. 80 columns is a well established
standard, for bloody good reasons. Why deviate? As far as I know,
Webware is the only large Open Source Python project that:
- uses Tabs
- has run-on lines
- consistently uses ''' instead of """ for docstrings.
Why don't we just follow the well established style guidelines for
Python and end this debate once and for all?

Maximum Line Length
There are still many devices around that are limited to 80
character lines. The default wrapping on such devices looks ugly.
Therefore, please limit all lines to a maximum of 79 characters
(Emacs wraps lines that are exactly 80 characters long.)
The preferred way of wrapping long lines is by using Python's
implied line continuation inside parentheses, brackets and braces.
If necessary, you can add an extra pair of parentheses around an
expression, but sometimes using a backslash looks better. Make
sure to indent the continued line appropriately. Emacs
Python-mode does this right. Some examples:
