Package: emacs
Version: 23.0.50
In the newest Emacs HEAD source, font-lock in cperl-mode is broken.
Here are the steps to reproduce the problem:
1. Start emacs:
$ emacs -Q
2. Visit an empty perl file and switch to cperl-mode:
C-x C-f x.pl
M-x cperl-mode
3. Type `print' (no any characters follow the character `t'):
print|
The vertical bar `|' here indicates the cursor. Now the word
`print' is highlighted with face `cperl-nonoverridable-face'.
4. Now that the cursor is after the character `t', type SPC to append
a whitespace character.
print |
This time, the word `print' gets unhighlighted. There is no
property `face' for that word now:
;; Point is in between `print'.
(text-properties-at (point))
==> (fontified t)
Appending more whitespace characters will not call the highlight
back. However, deleting all of the whitespace characters
highlights it again.
print | ;; Type DEL
print| ;; `print' gets highlighted again
And the face property is added back:
;; Point is in between `print'.
(text-properties-at (point))
==> (face cperl-nonoverridable-face font-lock-multiline t fontified t)
The same problem exists for larger Perl programs. This is only a
simple case.

Guanpeng Xu

This was my mistake; I've checked in a fix. Thanks.
