The two spaces after the period here are deliberate. Note that elsewhere in this file, periods have two spaces after them. This is used by some editors (including emacs) when a paragraph is re-flowed. I suggest putting this "extra" space back.

PEP 8 mentions this for comments. https://devguide.python.org/documentation/style-guide/ says one or two spaces is acceptable, but in this case I think we should match the rest of the file.

@ericvsmith There are other instances where there's only one space instead of two after a period in the file. Should I correct those too? :)

I beg to differ, @ericvsmith. We do not need to encourage contributors to "fix" one or two spaces after period. There's better use of both contributor time and review time. Also, what has PEP-8 with .rst files to do? AFAICS, nothing.

one that would be returned by ``min(entries)``). A typical pattern for
entries is a tuple in the form: ``(priority_number, data)``.

If the *data* elements are not comparable, the data can be wrapped in a class
that ignores the data item and only compares the priority number::
