Thanks, now I understand what you meant.

That was also my first approach, but then I thought I make it more
robust since we really don't know what people will choose as delimiters.
Actually, I think we have change that to:
(regexp (concat "[^\\]" (mapconcat #'regexp-quote strings "\\|")))
to exclude things like \|, \- and \" etc.

True, that was again only precaution. But I think we're not done yet.
Please consider this example, and hit 'M-q' in the paragraphs once with
`font-lock-mode' enabled and once disabled:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{shortvrb}
\begin{document}
Lorem ipsum |dolor| sit "amet", consectetur |adipiscing elit, sed do eiusmod|
tempor incididunt ut labore et dolore magna aliqua.
Lorem ipsum |dolor| sit "amet", consectetur \verb|adipiscing elit, sed do
eiusmod|
tempor incididunt ut labore et dolore magna aliqua.
\end{document}
%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% LaTeX-shortvrb-chars: (?| ?\")
%%% End:
--8<---------------cut here---------------end--------------->8---
with this definition:
--8<---------------cut here---------------start------------->8---
(defun LaTeX-verbatim-p (&optional pos)
"Return non-nil if position POS is in a verbatim-like construct."
(when pos (goto-char pos))
(save-match-data
(or (when (fboundp 'font-latex-faces-present-p)
(font-latex-faces-present-p 'font-latex-verbatim-face))
(member (LaTeX-current-verbatim-macro)
(LaTeX-verbatim-macros-with-delims))
(member (TeX-current-macro) (LaTeX-verbatim-macros-with-braces))
(member (LaTeX-current-environment) (LaTeX-verbatim-environments))
(when LaTeX-shortvrb-chars
(let* ((strings (mapcar #'string LaTeX-shortvrb-chars))
(regexp (concat "[^\\]"
(mapconcat #'regexp-quote strings "\\|")))
(p (point))
(match (save-excursion
(re-search-forward regexp (line-end-position) t))))
(and match
(save-excursion
(cl-oddp (how-many regexp (line-beginning-position) p)))
(save-excursion
(cl-evenp (how-many regexp (line-beginning-position)
match)))))))))
--8<---------------cut here---------------end--------------->8---
With `font-lock-mode' enabled, you get this:
--8<---------------cut here---------------start------------->8---
Lorem ipsum |dolor| sit "amet",
consectetur |adipiscing elit, sed do eiusmod| tempor incididunt ut
labore et dolore magna aliqua.
Lorem ipsum |dolor| sit "amet", consectetur
\verb|adipiscing elit, sed do eiusmod| tempor incididunt ut labore et
dolore magna aliqua.
--8<---------------cut here---------------end--------------->8---
and without, you get:
--8<---------------cut here---------------start------------->8---
Lorem ipsum |dolor| sit "amet", consectetur
|adipiscing elit, sed do eiusmod| tempor incididunt ut labore et
dolore magna aliqua.
Lorem ipsum |dolor| sit "amet", consectetur
\verb|adipiscing elit, sed do eiusmod| tempor incididunt ut labore et
dolore magna aliqua.
--8<---------------cut here---------------end--------------->8---
I think the issue is that '|' has also `font-latex-verbatim-face' which
makes Emacs travel to far back when searching for the next break point.
I'm not sure what's the best approach to fix this, what do you think?
Best, Arash
