Here is the patch.

Thanks!

I've removed the check_plain() frunction from the drupal_set_message call. Coder does not give a 100% pass now, however.

Here is the message:

Line 1018: Potential problem: drupal_set_message() only accepts filtered text, be sure to use check_plain(), filter_xss() or similar to ensure your $variable is fully sanitized. (Drupal Docs) [security_dsm]
drupal_set_message($message, $severity, FALSE);

Also, I agree that it is odd to ask for credit in the comments of a ticket. The reason I've begun to do it is because I've very rarely been attributed a commit without having to email the maintainers. For example, I've had this happen with 3 commits this week alone. After spending time sending the same e-mail over and over to maintainers and never getting the commit amended correctly, I've decided to simply attach it to the ticket with the patch.

I realize that my last comment may have been misleading. I only emailed module maintainers after my changes were committed without attribution. The purpose of said e-mails was solely to amend the commit so it included credit to the author. I never posted these sort of attribution comments before, but I got really tired of trying to get credit for my work after every patch I made. It's not intentional on the maintainer's part, but it does get frustrating and I wanted to save everyone unnecessary time and effort.
