bug#73302: TeX-find-closing-brace and verbatim macros

[Paul Nelson]

Hi Ikumi,

Sure, I'd be happy to work on this.

According to the documentation, TeX-verbatim-p always returns nil
outside LaTeX-mode, so it seems to me that to fix the issue you raise,
it would suffice to use that function in place of LaTeX-verbatim-p
(rather than doing derive-mode-p checks).  Does that sound right to
you?  (I never use the other modes, so my knowledge there is a bit
spotty.)

Thanks, best,

Paul
