Fixed in version 0.9.6: Added a placeholder #content# to include the comment's content in the e-mail notification.
Thanks for the enhancement. Can I know where to download the new version?
I am going to release 0.9.6 in about one week using the Atlassian Plugin Exchange.
If you want to test the feature earlier you may use the file attached .. but it's an alpha nightly build ;)
