I did spend a lot of effort on the "theming" -- both 2 years ago when we
started with Mercurial, and this year after some updates of Mercurial.
The setup of "shortlog" follows the idea of a "short log", without
linebreaks, while the longer formats do give the line breaks.
What I am trying to point out here again is that the maintenance of the
system is a huge effort. This can be simplified by following a few
trivial rules. The changelog history is one of the main assets, even more
important than the quality of the tip version of the sources, because the
history is fully persistent and cannot be modified later on.
