Subject: 24.4;
 *grep* output buffer not getting fontified when jit-lock-defer-time
 is used
Date: Mon, 27 Oct 2014 20:33:48 +0100

Recipe:

* emacs -Q

* M-x set-variable RET jit-lock-defer-time RET 0.05 RET

* Call M-x rgrep and search for some string in some directory

You should be able to see that the *grep* buffer capturing grep's output
is not getting fontified until you hit a key. I would expect that it
gets fontified automatically when new output arrives.

Note that the same problem happens for other buffers which capture
process output, like compilation buffers.

I made the requested change in keyboard.c, and committed both parts,
with the compile.el part on the emacs-24 branch.

Closing.
