Bug#408641: asks user to select disk to partition, even if there's only one disk

[Robert Millan <rmh@aybabtu.com>]

Package: partman
Severity: normal

Partman (guided partitioning) will still ask the user to select which disk to
partition, even if there's only one disk.

Maybe the fix could be implemented in debconf/cdebconf:  when a multiselect
question only has one possible answer, it could be skipped automaticaly.
