Comments Return Email Body

After submitting a comment, a page looking like the following is returned.

Array
(
    [body] => Greetings, someone.

A content type to which you have subscribed has been updated.



To view the thread, navigate to http://example.org/node/ 

--
This is an automatic message from Example.
To manage your subscriptions, browse to http://example.org/user/4/subscriptions
    [subject] => [Example] content type subscription update for someone : 
)

Other than seeing that strange page, everything seems fine (the comment is posted when you look at the node and subscriptions go out).

Maybe lines 463 & 464 (of version 1.62.2.14), part of the subscriptions_mailvars function, are to blame? Maybe it's just accidentally left-in debugging code?

print "<pre>";
print_r($mail);

The lines were introduced in subscriptions.module version 1.62.2.12.

I'm a noob, so not sure. I commented those two lines out of my installation, we'll see how it goes.

I'm excited about what this module can do. Thanks to everyone working on it!
