Comment (by jmroot):

 If we abbreviate the path at all, we need to handle collisions, maybe by
 storing the full path in a file. And if we're doing that, maybe we might
 as well abandon any attempt at human-readability and just use something
 like a short checksum of the path. Most of the time you're going to be
 using command like `port work` to find the path anyway, and if you have to
 look in there manually, the next subdir down still has the subport name.
