portmaster overzealous on distfiles?

[Andriy Gapon]

I run the following command to upgrade from audacious 1.5.* to 2.0.*:
$ portmaster audacious\*
This starts to build three ports: audacious, audacious-plugins, audacious-skins.
At the end of audacious upgrade portmaster asked me if I want to delete not only
the older distfile of audacious but also about the newer one, and the one for
audacious-skins.
