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.
Workaround:
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.

It used to have symbol syntax, and then I changed some fontification
code which required that it became some non-symbol syntax. I chose
paired delimiter because it seemed to be convenient in my typical use
(lots of \verb|stuff|) because then typing | would insert a pair of bars
with `electric-pair-mode'.
Well, that was obviously a bad decision, so now AUCTeX uses punctuation
syntax for it. That will appear in 11.88.8 from ELPA then.
Bye,
Tassilo
