This does several things to reduce the number of warnings generated in a
docs build.
. Only generate the {ptl,tc}.rst for the type of election we're running
. use a for loop to match the undreline with the section title
. Ensure that we use anonymous hyperlinks ``__ vs ``_
. tell sphinx to ignore the generated announcement as they're not linked
There are still 4 left which look to me like actual bugs in
sphinux/docutils rather than our RST.
