Agree - I don't want to add any special behaviour to suppres_.

Well, yeah.  That would be my fault - let's fix it up to be backwards
compatible again though.  Please, please - when you do tests, look at
Cassandane and see if you can get a test in there.  Talk to Greg (gnb,
CC'd) about it as all...

A lot of stuff that was broken in 2.4 was broken because I didn't use
it, and didn't know it well enough to be sure what I was breaking in
the process.  We're going to be a bit more careful with 2.5.  With 2.4
it was "we haven't had a release in over a year, and if we don't get
this stuff out the project is just going to slowly rot".

We can afford to be a bit more careful this time around.
