highlight-lines-matching-regexp doesn't work as it should after having
reverted a buffer.

Reproduction:
1. Open a text file with any relevant contents.
2. M-x highlight-lines-matching-regexp and highlight something in the file.
3. M-x revert-buffer RET yes RET
4. Now the highlighting is gone, which I can accept, however...
5. M-x highlight-lines-matching-regexp RET RET
6. Nothing is highlighted this second time!

I've checked in a fix.

(This is actually a manifestation of Bug#635, "Adding font-lock keywords
results in no font-lock at all".  I added a hack to hi-lock-mode to work
around this bug, and the hack can probably be reversed if/when 635 is
fixed.)
