Patch enabling after-revert-hook for auto-revert-tail-mode

[Denis Bueno]

Dear emacs-devel:

A while back I wanted two things to interact the way I expected:
hi-lock-mode and auto-revert-tail-mode. I wanted terms highlighted by
hi-lock-mode to continue to be highlighted after a revert by
auto-revert-tail-mode. But my hook (which refontifies the buffer)
wasn't getting executed after a revert.

The reason is, of course, obvious: after-revert-hook wasn't called. My
patch calls it  at the most obvious place I could think of.

It's a one-line change -- not much can go wrong, I think. I have been
using this change for many months now (and have recompiled emacs 6-8
times during that period). Please consider applying it. It is useful,
and seems like this is the way it should be  -- after-revert-hook
should happen after reverting the tail of the file.
