[climacs-cvs] CVS update: climacs/Doc/climacs-internals.texi

[Robert Strandh]

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.
