FTR, I relaxed the PEP-8 requirements in my script for long lines from
80 to 100 -- there were a significant number of lines that violated the
80 character width, and considerably less that violated the 100
character width.

I'll revert this change as you suggest, and then run a pass of the
script looking only for long lines and open a separate issue for them.

It's my understanding that these are needed for docutils to consider the
two sections part of a contiguous literal block.
