Subject: 30.0.50; rainbow-mode highlights quoted text in man pages
Date: Mon, 28 Aug 2023 11:42:19 +0200

When rainbow-mode is enabled in buffers displaying man pages (both 
man and woman), the `font-lock-string-face` is applied to text 
between quotes.  AFAIK, man pages don't require the use of closing 
quotes which causes entire sections to interpreted as if they were 
quoted strings.

To reproduce this, install and load the package, then:

(add-hook 'Man-mode-hook #'rainbow-mode)
(man "git-config(1)")

Scroll up until you see the wrongly fontified text.


One way to mitigate this is to add

(modify-syntax-entry ?\" "." table)

to the syntax tables.
