Comment 1 for bug 239158

Indeed, this is very strange.
Steps to reproduce:
1. Logged in as Sample Person, open http://answers.launchpad.dev/firefox/+question/4
2. Subscribe to that question
3. Add a comment: "foo bar -- foo"
4. Add another comment: "foo bar"

What happens:

The email sent on step 3 is similar to the one described in this bug report, the footer has no "--" separator.
The email sent on step 4 looks right, with a "--" separating the body from the signature.

What should happen:
Both emails should look like the email sent on step 4.
