Oh, I see, thanks.  That's unusual of cperl-mode to do that, but it's
probably a good idea.

No need to debug.  Just check out old versions of fill.el from the Emacs
CVS repository and try them, using the "binary search" approach.

There's been 33 versions since Emacs-21.3, so a binary search will tell
you which version is the culprit (if the culprit is in fill.el) in
only 5 steps.

Sure, fill-paragraph should work fine in 90% of the cases, but
cperl-fill-paragraph probably handles a few more special cases.
Then again, maybe not (but Ilya is usually pretty thorough).
