I very much hope that Roland's after-save-buffer-hooks code gets integrated
into the official distribution; the fact that this variable didn't exist
already is the reason that tar-mode and the various compress/encrypt modes 
do not get along.  

The thing that these modes have in common is that they need to alter the
buffer contents before saving, and change it back afterwards.  They do this by
using a write-file-hook that actually writes the file.  This means that
following hooks will not get called, which means a compressed or encrypted tar
file may be visited, but it either cannot be written out compressed/encrypted,
or it will be written out as a garbled tar file, depending on whether
tar-mode's hook or crypt-mode's hook made it on to the write-file-hooks first.
