Adding % to `ispell-tex-arg-end'

[Arash Esbati <esbati@gmx.de>]

Hi all,

when I run Ispell over the following snippet, the second [htbp] is
matched by Ispell:

\begin{figure}
  [htbp]
  \caption{foo}
\end{figure}

\begin{figure}%
  [htbp] % <== matched by Ispell
  \caption{foo}
\end{figure}

It is due to the regexp in `ispell-tex-arg-end':

(defun ispell-tex-arg-end (&optional arg)
  "Skip across ARG number of braces."
  (condition-case nil
      (progn
	(while (looking-at "[ \t\n]*\\[") (forward-sexp))
	(forward-sexp (or arg 1)))
    (error
     (message "Error skipping s-expressions at point %d." (point))
     (beep)
     (sit-for 2))))

Would it be possible to add "%" to this function?

(defun ispell-tex-arg-end (&optional arg)
  "Skip across ARG number of braces."
  (condition-case nil
      (progn
	(while (looking-at "[ \t\n%]*\\[") (forward-sexp))
	(forward-sexp (or arg 1)))
    (error
     (message "Error skipping s-expressions at point %d." (point))
     (beep)
     (sit-for 2))))

I hope that nobody writes such LaTeX code, but Ispell should match valid
code here.

Best, Arash
