Without whitespace highlighting, your change threw me for a sec.. But
yeah, having the overline is inconsistent with other headings in the
doc.

What I wanted to ask about was the linelength as I don't know anything
about rst. Is it possible to avoid having the ~150 character line or is
that a necessary evil?

Thanks,
Conor.
