Before this, if a vc project was in the user's home directory,
project-root would be "~/some/path".  This violates the spec of
project-root, which requires an absolute path.  One concrete bug
caused by this is that (project-forget-project "~/some/path") would
work but (project-forget-project "/home/user/some/path") would not.

I ran into this while trying to use file-notify to automatically
discover and forget projects.  file-notify returns truly absolute paths,
so I ran into the aforementioned concrete bug.
