OK, I've committed a fix to trunk.  Instead of doing away with the BUF_*
macros, I reworked them to handle the indirect buffer case properly.
This means they can no longer be used in `BUF_PT (foo) = bar' assignment
statements, so I've changed the callers that used them this way.

Not sure if the patch is appropriate for the emacs-23 branch, though.
