So this is separate from the patch series itself in a way, but it brings a
question to mind:

I wonder how much longer we really need to support any of:

 - Python < 3.n (where n=5 or 6 maybe)
 - Sphinx < 1.7 or even some 2.x

We're carrying a certain and growing amount of cruft to handle these
cases.  I might start putting together a series to clean this up for 5.11
or so.
