tex argument handling gets "error skipping s-expressions at point" if argument looks like a URL and includes "list"

[boyland]

The problem is that tex arguments that have a certain form cause ispell to crash with a "Error skipping s-expressions"

Here's how to duplicate the error. Put the following a buffer (say for test.tex):

Hello

\url{https://lists.nongnu.org/archive/html/emacs-devel/2024-08/msg00955.html}

\foo{xtp:foolissy.com}

\foo{xtp:foolisty.com}

\foo{foolisty.com}

Bye

Then run "ispell-buffer". It will give errors on the \url argument and the second \foo argument. By error, I mean that it prints "Error skipping s-expressions at point N" and then beeps and waits a second or two and then continues.

It ignores the first call of \foo (not sure if that is a bug or not -- I don't care) and
It (correctly) finds a spelling error on the third \foo argument.

With some testing, It appears that the bug is activated if a tex argument looks like a URL (has name "colon" text "dot" name) and includes the letters "list" in this order.
