master 66efb2f 4/4: Fix "dnl" highlights in m4-mode

[Lars Ingebrigtsen]

branch: master
commit 66efb2f3a636868ada730c2f472f070a51f3c6b2
Author: Lars Ingebrigtsen <address@hidden>
Commit: Lars Ingebrigtsen <address@hidden>

    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.
