  Right, and I see now you wrote that this is how the bash completion
works.  From the above output it looks pretty clear that foo is a pure
virtual package, but it's present in the apt cache. (I'm not sure why)

unless you pass "-o Apt::Cache::AllNames=false" on the command-line.
I'm a bit puzzled about why this is needed, since it looks to me from
the source like "false" should be the default.
