When in c-ts-mode.el and when having '(setq comment-end " ")' and when I
then
then run e.g. 'comment-dwim' or simpler '(comment-normalize-vars)', I'm
getting
'comment-dwim: Args out of range: "", 0, 1'.
The error comes from the two 'substring' calls in this s-sexp - where the
code
already contains my "fix" - both calls to 'substring' have been guarded by
'(if (string-equal ce "") "" ...)'.
There are surely smarter ways to fix that - if one knows what is supposed to
happen here :). But maybe that fix gives you a hint to the appropriate
solution.
