Subject: Fix "dnl" highlights in m4-mode
X-Git-Tag: emacs-27.0.90~821
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=66efb2f3a636868ada730c2f472f070a51f3c6b2;p=emacs.git

Fix "dnl" highlights in m4-mode

* lisp/progmodes/m4-mode.el (m4-font-lock-keywords): "dnl"
comments should override any previous syntax-based highlighting
(37132).  This makes "dnl foo#bar" be highlighted correctly.
