In practice it seems to work well, even at 79 chars.  The default is 88
and I don't think the extra 8 or 9 columns are enough to make a different
rule for Python worth it.

FWIW, personally I use an 80-column editor for GCC stuff, and it would
be a pain to have to switch to something different to work on Python.

IMO the real value is if it's the defined approach, rather than an
optional approach.  It's "format and forget", just like with clang-format.
