Subject: 24.3.50; No fontification in Info mode
Date: Sun, 24 Feb 2013 23:43:57 +0100

Hello Emacs devs,

In Info mode, fontification is not happening.  Recipe to reproduce:

  $ emacs -nw -Q

Once inside emacs,

  1. C-h i
  2. TAB (to go to the first menu entry)
  3. M-x describe-face RET (you will see it is default)

I also tested this without no-window, I get the same issue.  Hopefully I
have provided enough information.  If you more info, let me know.

Cheers,

I confirmed it has been fixed on:

Sorry for the noise.
