Subject: 25.1; cperl syntax highlighting broken
--text follows this line--
When inside a cperl HERE doc, using any function that inserts a newline at the start of a line will causes the rest of the file to highlighted with font-lock-comment-face. The only way to fix this is to make changes to the correctly highlighted part of the HERE doc which causes it to re-parse. My guess is that cperl is getting mixed up with POD highlighting and trying to apply cperl-pod-face since POD's and HERE documents are very closely related in cperl-mode code.
To reproduce:
use the minimal cperl-mode file below
---------------------------------------------
my $here_doc = <<'_HERE_';
this is here doc line
_HERE_
---------------------------------------------
call `M-: (insert "\n")` when cursor is at the start of any line
inside the HERE doc.
You will see that the rest of the file is highlighted with the comment face. Calling any function that finds the HERE doc region will be incorrect (e.g. cperl-narrow-to-here-doc)
