Good thought, but that is not the case. I am deleting the comment tags after every run.

Here is the original code copied/pasted directly from one of my pages:

            <cfmail to="#to_address#" 
                ....
            </cfmail>
[download]

Now, I just ran the script again and got (again, copied directly from the page after the script ran):

            <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--
+- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <!--- <
+!--- <!--- <!--- <!--- <cfmail to="#to_address#" 
               .....
            </cfmail> ---> ---> ---> ---> ---> ---> ---> --->
