Bug#985899: apt bash-completion should complete build-dep ./somefile.dsc

[Helmut Grohne <helmut@subdivi.de>]

Package: apt
Version: 2.2.2
Severity: minor

In bash,

$ apt build-dep ./foo<tab>

does not complete an existing file foo.dsc, while apt would happily
consue it. It only completes bare package names.
