Interesting! In these cases, actually, I like having the slash and plus
be a one-character "word", I find editing the sentence much more
intuitive. But I did notice that now, `transpose-words' can produce some
ugly results. Before, with point between the two words:

/Fortress Beseiged/ -->  /Beseiged Fortress/


/Beseiged Fortress/ --> Fortress/ /Beseiged

Not so good. Perhaps what I actually want is to give these markup
characters "parenthesis"-type syntax. I'll give that a shot.

Editing preferences are subjective, but I'm also worried this will play
havoc with export/tables/table formulas/source blocks. I'll just run it
for a while and see what breaks.

Thanks for the input.


FYI, here's what I'm using, in a hook:

--8<---------------cut here---------------start------------->8---
(defun my-emph-to-word ()
  (when (eq major-mode 'org-mode)
    (mapc (lambda (x)
            (modify-syntax-entry (string-to-char (car x)) "w"))
--8<---------------cut here---------------end--------------->8---
