If the path we are trying to print doesn't exist see if it matches an
aliases. We don't do anything fancy at this point, but just strip the
leading '/' if it exists and see if we have an exact match to an alias.
In the future we could try and prefix matching so the alias could be used
as a shorter path reference.
