[Message part 1 (text/plain, inline)]
In tex-mode, latex-forward-sexp does not correctly handle parentheses
like this \[ \]. In particular, it says the expression is not balanced
when it is.
Steps to reproduce the bug:
1. Start with emacs -Q (with -nw or without doesn't make a difference)
2. Open any .tex file (I attached test.tex which I used).
3. Navigate to any LaTeX equation delimited by \[ and \], like this:
\[ 1 + 1 = 2 \]
4. Put the cursor on the first [ in the line:
5. Call latex-forward-sexp
That's it. On test.tex, the error I get is:
Scan error: "Unbalanced parentheses", 126, 157
Note that if the cursor is on the backslash, rather than [, then there
is no error.

I think that's correct behaviour? The parentheses start is \[ and not
just [.
Anybody have any opinion here?
