Update of /project/climacs/cvsroot/climacs/Doc In directory common-lisp.net:/tmp/cvs-serv18511/Doc

Modified Files: climacs-internals.texi Log Message: Modified the buffer protocol to contain a modification flag, and implemented the modification. Updated the documentation.

Added a flag to the climacs-buffer indicating whether the buffer needs saving. This is different from the modification flag, which is only valid during one iteration of the command loop. The needs-saving flag checks the modification flag, though, after each command execution.
