In the newest Emacs HEAD source= =2C font-lock in cperl-mode is broken.
Here are the steps to reproduce t= he problem:

1. Start emacs:

 =3B =3B =3B =3B = $ emacs -Q

2. Visit an empty perl file and switch to cperl-mode:
=
 =3B =3B =3B =3B C-x C-f x.pl
 =3B =3B = =3B =3B M-x cperl-mode

3. Type `print' (no any characters follow= the character `t'):

 =3B =3B =3B =3B print|

=  =3B =3B The vertical bar `|' here indicates the cursor. =3B No= w the word
 =3B =3B `print' is highlighted with face `cperl-nono= verridable-face'.

4. Now that the cursor is after the character `t'= =2C type SPC to append
 =3B =3B a whitespace character.

&= nbsp=3B =3B =3B =3B print |

 =3B =3B This time= =2C the word `print' gets unhighlighted. =3B There is no
 =3B&nb= sp=3B property `face' for that word now:

 =3B =3B =3B&nb= sp=3B =3B=3B Point is in between `print'.
 =3B =3B =3B = =3B (text-properties-at (point))
 =3B =3B =3B =3B = =3B =3B =3B =3B =3B =3D=3D>=3B =3B (fontified t)
<= br> =3B =3B Appending more whitespace characters will not call the = highlight
 =3B =3B back. =3B However=2C deleting all of the = whitespace characters
 =3B =3B highlights it again.

 = =3B =3B =3B =3B print | =3B =3B =3B =3B =3B=  =3B =3B =3B =3B =3B =3B =3B =3B =3B&nb= sp=3B =3B =3B =3B =3B =3B =3B =3B =3B = =3B =3B=3B Type DEL
 =3B =3B =3B =3B print| =3B = =3B =3B =3B =3B =3B =3B =3B =3B =3B =3B=  =3B =3B =3B =3B =3B =3B =3B =3B =3B&nb= sp=3B =3B =3B =3B =3B =3B=3B `print' gets highlighted again=

 =3B =3B And the face property is added back:

 = =3B =3B =3B =3B =3B=3B Point is in between `print'.
 =3B=  =3B =3B =3B (text-properties-at (point))
 =3B =3B&n= bsp=3B =3B =3B =3B =3B =3B =3B =3D=3D>=3B =3B= (face cperl-nonoverridable-face font-lock-multiline t fontified t)

= The same problem exists for larger Perl programs. =3B This is only asimple case.
