color coding wishlist request/setting/bug

Hello all,
this is my first post to this list.
I've been using quanta plus for about a year now and I love it.
I have come across three related cases that mess up the colour coding, and I'm 
wondering if I have a setting wrong, or If I should file a wishlist request 
or a bug report. All three involve colour coding within a php heredoc string.
examples follow:

$var = <<< EOT
http://www.example.com
EOT;
everything after "//" is colour coded as a comment 

$var = <<< EOT
<?xml version="1.0" ?>
EOT;
everything after ?> is colour coded as if it were back in html mode.
putting the next line "//<?php"
is a work around


$var = <<< EOT
joe's house
EOT;
colour coding indicates that the single quote starts a string.

Thanks for the great product
Ray
