Fascinating. As soon as I start working on documenting and prettying up the debugger, people start patching it. I dunno if this is just The Great Magnet at work or what. Three patches so far in the past week. Hmmm.
And now (2/21) major restructuring of the commands. I take this as a Sign From Above that I should wait awhile before submitting the big reformatting patch. At least until things settle down a bit.
