Subject: [PATCH] Remove notion of 'current directory' from the file handling
 for UNIX systems.  Pathnames are always accessed internally as full/absolute
 pathnames, and while they can be loaded and saved with the '~' symbol (to
 indicate the users home directory), they are still always mapped to absolute
 paths.
