bug#20860: 24.4; python.el's fill-paragraph incorrectly handles doc-stri

Confirmed with `emacs -Q`.

The default `fill-column` is 70 characters. So, running `fill-paragraph`

on a doc-string line that is over 70 characters should wrap to leave

under 70 characters. All the lines after the first one work

correctly. However, the first line gets wrapped to 74 characters

instead.

An example function can be found here:

https://gist.github.com/topher200/9b04870d74e26682adde

In the example, running `fill-paragraph` should put my `SHOULDBEWRAPPED`

string on a new line. It incorrectly stays on the first line; 74

characters remain on that line, way over our `fill-column` of 70.
