Many modern mail clients, such as Evolution and Thunderbird, look for
keywords in the message body that indicate a likely attachment (such as
"attached" or "attachment"), and warn if attempting to send that message
without an attachment.  Since reportbug does not support attaching a
file while composing the message, only after composition and before
sending, it becomes even more likely that the user will forget an
attachment.  Please consider adding a check for this.

Evolution uses the following keywords:
attachment
attaching
attached
enclosed
