Special handling for import paths containing explicit 'vendor'?

It's possible to directly import out of vendor. That is,

import "github.com/sdboyer/gps/vendor"

Doing so would cause errors in PackageTree's extraction methods. A similar issue exists for godep with rewritten imports.

We need general handling for these cases.
