[SciPy-Dev] Configuration in tox.ini tells pep8 to ignore E501 (line too long).

[Warren Weckesser]

Currently, tox.ini tells pep8 to ignore line length, but it also sets
`max_line_length=79`.  I don't recall if there was a decision to allow
long lines, or if this is just to avoid all the output that would be
generated if we didn't ignore it.  I'd like to remove E501 from the
`ignore` list.  Any objections?
