Subject: Don't leave old channels laying around
X-Git-Tag: v3.0.7~1
X-Git-Url: http://git.scottworley.com/pinch/commitdiff_plain/fc168c346f74912eee2377a28c583fe63889b1de?hp=b11f21b085df77bd26f1c0c41a78e3ca953267e5

Don't leave old channels laying around

* The channels present should be deterministic -- exactly those
  specified in the pins file.  The history of which other channels have
  been installed should not affect this.

* Before this change, when a channel changes names only slightly, the
  old channel could block installation of the new channel.
