Comment 2 for bug 1512843

I agree with Chris that reports should tell you when they're done, regardless of the content. In fact, I'd go further and suggest that this is something we should not allow. There's a strong analogy to overdue notices here, where if there are no notices to generate the assumption by staff is often that something went wrong instead of that everything is working as intended.

Instead, I think it would be useful (and should be possible) to include the number of rows that the report contains in the email. Then, if it's zero and that's the expected case requiring no further attention, the email can simply be ignored.

Thoughts?
