Wanted to add some debugging code to see if I could catch some bugs during the evening's operation... turned into rather a lot of bug-fixing and minor feature implementation work that bring's the day's total to some entirely improper number of hours (sorry hands). I have to stop now or I won't be able to either sit or type tomorrow.

[Hmm, and later on, at 01:48, I'm still working... bah. Must sleep]
