Comment 15 for bug 201749

That is a valid use case, and that's what this bug is about.

However, 'needs review' is currently used like this:

As a reviewer, you go to a message that has:

 Current: "1+1=2"
Suggestion: "1+1=3"

New suggestion: "1+1=2.5"
[x] Needs review

The ending situation should be:

 Current: "1+1=2"
Suggestion: "1+1=3"
Suggestion: "1+1=2.5"

This is the behaviour that we shouldn't break. Figuring out the when to do which is hard.
