bug#41442: 26.3; `forward-sexp' in LaTeX mode

[Drew Adams]

Dunno whether this is a bug (haven't used LaTeX in 30 years).

See https://emacs.stackexchange.com/q/58644/105

Seems like `forward-sexp', with cursor before the `{', should move past
the `}'.  Instead, it takes account of parens in between: if they are
balanced then it moves to the `}'.  Else it moves to a `)' that seems to
balance the `{'.

In LaTeX does it ever really make sense for `)' to balance `{'?
If not, then I think we have a bug.  Hopefully someone familiar with
LaTeX will be able to judge.
