Accommodate PR numbers in wiki version log format
Accommodate PR numbers in wiki version log format

I now also keep track of PR numbers when writing out version logs. I've
elected to surround it with parens for easy matching and parsing.

The JSON-based changelog format simply ignores the PR number, as does
the flat version log format.

A separate 'pr' version log format is created specifically for
outputting all PR numbers, designed for conveniently pasting both the
flat and the PR formats into different columns of a spreadsheet.
