Hi,

I'm sorry for being very late on this issue.

After trying to reproduce all cperl-mode bugs from the Debian BTS,
it seems that most of them have been fixed in the CVS trunk, but
one which is a regression from the original CPerl-mode from
Ilya.

Could you please take care of this?

Thanks in advance.

Here is the bug report:

-------------------------------------------------
The following bug report seems to be fixed in 4.32 but I could
reproduce it with 5.0 from the Emacs CVS.

Subject: emacs21-el: keyword highlighting bug in cperl-mode.el
Message-ID: <Pine.LNX.4.33.0111231840220.3595-100000@salmon.pepperfish.org>
MIME-Version: 1.0

Delivered-To: submit@bugs.debian.org


Package: emacs21-el
Version: 21.1-2woody
Severity: normal

subroutine names which contain built in keywords/function-names
delimited by _ characters get highlighted incorrectly:

For example, in emacs20-el:

sub foo_print_desc ()
{

}

'foo_print_desc' gets highlighted in font-lock-function-name-face
whereas under emacs21-el the 'print' part gets highlighted in
cperl-nonoverridable-face and the foo_ and _desc parts don't get
any highlighting at all. (This may be a bug in emacs21, of course)

The emacs package is one I compiled from source on woody, but I didn't
make any changes to the source - the sid system here is down at the moment,
but it should be easy to check that the bug exists there too...
