Description: Call os.path.expanduser in the collect function instead of top level
 Calling it when defining the PATH or paths variables meant the
 value of os.path.expanduser("~") ended up as part of the default
 function signature, which makes this unreproducible.
 Also I think ~ is a bit clearer to the user, at least Unix-like OS users.
