25.0.50; Regression: highlight-lines-matching-regexp can't re-highlight the same string |

Hi.
The following commit broke some hi-lock functionality:
commit 6711a21f1125c0047c56eb266eb374c1ec90a967
Author: Stefan Monnier <address@hidden>
Date: Wed May 28 23:45:29 2014 -0400
...
* lisp/hi-lock.el (hi-lock-mode, hi-lock-unface-buffer)
(hi-lock-set-pattern, hi-lock-set-file-patterns): Use font-lock-flush.
...
Recipe to reproduce:
1. seq 1000 > /tmp/dat
2. emacs -Q /tmp/dat
3. M-s h l 7 (highlight all lines matching "7")
4. M-s h u [enter] (un-highlight the default, "7" in this case)
5. M-s h l 7 (highlight all lines matching "7" again)
After that commit, nothing is highlighted anymore

Yuck, the old behavior looked right but was subtly wrong (the
highlighting at step 5 was done via font-lock whereas it was done with
overlays at step 3), and the recent change made the difference "more
visible" ;-)
The real problem is in font-lock, I think, but I don't have the courage
to fix it now, so I've installed a workaround that I hope will be sufficient.
