Hi all,

I just upgraded to a new version of Linux/emacs/org-mode, and am finding
that fill-paragraph (M-q) runs very slowly in org-mode on large files.
With about 50k lines in the buffer, fill-paragraph takes around 3 seconds
even if the paragraph is only a couple lines.  (The behavior is correct,
the problem is just the slowness.)  The time seems to scale linearly with
the number of lines in the buffer as if the whole file is being processed
during each fill-paragraph.

I have tried (setq  fill-paragraph-function nil) in an effort to use emacs'
default fill function instead of org mode's, but that did not fix the
problem.  When switching to text-mode the problem goes away.  I have also
tried running emacs with no customizations, and the problem is still
present in that case.

Things used to work fine in the versions of emacs and org-mode that I was
previously using, but those were a few years old and I am not sure exactly
which versions they were.  I am not using linum (I've seen that mentioned
as a cause of slowness).  Output from org-submit-bug-report is below.

Any help would be appreciated!
