Well, it took me a long time, but I figured out a bug
in my test code that made it look like parse had a bug.
It's not whitespace, but I still feel foolish now :(
I formally apologize for the Feedback messages I sent.
Reviewing the SELMA source I can't reproduce the bug
I found before so it must have been fixed. Good!
Another thing I haven't figured out is how Gabriele is
able to consistently end up with a Re: after the list
tag on all of his posts. It's not the messed-up thread
sorting that results from this that gets me, it's that
everything I can find in the SELMA source tells me it's
impossible to do that! It's this behavior that got me
searching the SELMA source in the first place.
I hate it when I can't track down a bug :(
