bug#21366: 11.88.6; Vertical bar is paired delimiter in syntax table

The vertical bar (|) is paired delimiter/math mode ("$") in the TeX syntax table. This means that balanced vertical bars are expected just as balanced parentheses. This causes problems with S-expression movement and Flyspell when there are odd numbers of vertical bars. The easiest way to reproduce a problem this causes:

1. Create test1.tex with contents:


2. Go to beginning of buffer and type C-M-f (forward-sexp)

What I expected to happen:

Cursor moves to last closing curly brace.

What happens instead:

I receive the error:

forward-sexp: Scan error: "Unbalanced parentheses", 1, 11

This sort of unbalanced vertical bar is likely to happen in table definitions.


Add this to .emacs:

(with-eval-after-load 'tex
   (modify-syntax-entry ?| "." TeX-mode-syntax-table))

I don't understand why | is treated as a paired delimiter in the first place, though.
