Bug#873610: dget:dget: does not preserve timestamps

[Thorsten Glaser]

Package: devscripts
Version: 2.17.9
Severity: minor

When I call dget with a path to a .dsc, it and its subfiles are
downloaded and stored with the current timestamp.

When I use wget on the same path, with no special options, the
timestamps from the archive are retained.
