Bug#990451: (no subject)

[Chandler Sobel-Sorenson <chandler@genome.arizona.edu>]

I concur and also request `--no-all-versions` apply to `apt-cache
policy` command as well.

Perhaps, instead, a new option with argument `--versions=N` could be
implemented, allowing a limited number of versions to be returned, with
`--versions=0` or `--versions=none` being the equivalent of
`--no-all-versions`.
