sigh. with ~1000 patterns in my collection of test scripts, one could have hoped I'd seen it all. but that's a new one.
umm. I'm not sure I want to check this one in. of all stupid bugs... I really gotta do something about that regression test suite.
(don't worry, the patch is on its way. unfortunately, my setup is botched, so I cannot test drive IDLE myself. or to put it another way, I cannot guarantee that this is the last problem with IDLE+SRE...)
