From 6848a6fa844ceec20a3da7bad13f418ff3dae5d6 Mon Sep 17 00:00:00 2001 From: Max Nikulin Date: Wed, 15 Mar 2023 19:08:37 +0700 Subject: [PATCH v2] org-manual.org: $n$-th is not math MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * 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 - Eric S Fraga to emacs-orgmode.
