That's weird, I'll look into it, thanks.

Sorry, I don't see the difference between these two. Did you write the
correct one twice by mistake?

No, there are no known bugs so please report everything you find!
exactPrint is new and most likely sparsely used as of yet. I'd expect
there to be a few bugs lying around here and there, and I appreciate
all reports!

No. Like Lennart points out that's a really difficult problem, not to
say impossible, where do you place the comments after reformatting?
