Yes, I got this from his article.  However, it seems that "[^\nf]*foo"
would succeed, avoiding the stack explosion.  So, it is possible to
rework the regexpes around the limitation.

Surely not a fun job to do for Org regexpes, I know.  Maybe not worth
doing as very long lines are unusual, yet maybe worth doing nevertheless
for Org files because long lines are still possible.  The fact is that I
was hit by this problem in the Org buffers generated by org-grep.

However, as I am tempted to think that the problem is unlikely to be
solved soon, I tried to alleviate it.  org-grep now shortens the lines
by removing, within each line, a good part of the context between hits.
This does not guarantee that the above problem will never occur, but it
considerably decreases the chance that it occurs.

Thanks for these hints, which I saved on keys here! :-)

Sure.

My little problem was different.  If I use Org in-line markup, like
bold, italics, or links to Web sites, or even block markup like
fragments between #+BEGIN_SRC and #+END_SRC, say, I was wondering how
this is best transmitted within a message, in the text, without
resorting to an attachment.  Gnus as a reader surely has some capability
somewhere, as I think I saw messages displaying Org code nicely; I just
do not remember how it was done.  Outside Gnus, it might be more
problematic to find a useful way to have Org included.  Sending Org all
raw is sometimes a bit noisy, especially for links.

Someone recently mentioned org-mime.el, new to me, maybe this is the
proper avenue?  I should at least play and experiment with it! :-).
