[Python-Dev] Why does PEP 7/8 explicitly suggest 2 spaces after a period?

In Emacs, the paragraph reflow commands still try to keep a period
followed by only one space together on a line, under the assumption
that it might be something like `Dr. Brett Cannon`. A reasonable HTML
generator should ignore the second space. So all in all I still like
the two-space rule -- not so much for readability but because of
tooling.
