trash --keep is not downloading vendor files

[greenpau]

Version info:

VERSION:
   v0.3.0-dev

I am running, trash --keep, nothing happens except for the following log messages:

DEBU[0000] dir: '/home/greenpau/go/src/github.com/greenpau/testrepo'
INFO[0000] Trash! Reading file: 'vendor.conf'

If I run trash --update and then run trash --keep, it does download the packages, but it also updates Git version references in vendor.conf.

The desired outcome is to run trash --keep to download dependencies to .vendor directory. The versioning of the dependencies should be based on the versions in vendor.conf.
