control commands in replies to existing bugs

[Glenn Morris]

I noticed some people try to use control commands at the start of
replies to existing bugs. This doesn't seem to work. It only seems to
be documented that one must send such commands separately to
address@hidden, but I just wanted to check that was the case.
