Code review comment for lp:~mbp/bzr/224373-2.2-ftp-response

I had mixed feelings about whether something that's a workaround for a
bug elsewhere, and not automatically tested, ought to go into stable
series. 2.2 was kind of a compromise. On the whole I might put it
only into 2.3. One of the affected users offered me access to an ftp
server to at least test it interactively.
