commit 07ea7fc4432185b2edaeb170ac2ef66a5c20e5ef
Author: Max Nikulin <manikulin@gmail.com>

org-manual.org: $n$-th is not math
* doc/org-manual.org (LaTeX fragments): Do not state that dash is
allowed after single "$" math delimiter and recommend "\(...\)".
Detection of "$-" as closing math delimiters has been broken since 2015
as a side effect of using punctuation class in regular expressions while
dash is considered as a word constituent. See commits
6779f8f424 and c0369a7984. Bring the manual in accordance to the code
instead of allowing "($-2 change)" false positives. Users who do not
like "\(...\)" constructs may use a helper for typing it and may change
how it is displayed to minimize visual noise by fontification, see
