Hi Ansgar,

I believe Britney already handles this reasonably[1].  Of course, I
assume here that by "ignore" you mean it is (also) okay for Britney not
to include them in the resulting HeidiResult file.

Assuming there will be a source package in Sources only kept due to
Built-Using, then Britney may (or may not) keep its counterpart in
testing until the source package disappears from Sources (in sid).  If
it does not have any binaries and it is not in testing, then she will at
least keep it out of testing[2].

It is possible I am missing a corner case or two, so I am keeping the
bug open for now.
