A sawmill menu, in XEmacs the inherited "Emacs-Lisp" menu is removed from the menu bar, the describe and apropos functions now identify constant values, a fix for symbol completion (would get carried away when deciding if it should pop up a list of symbols), and new sawmill-console and sawmill-interaction options.
`sawmill-describe-ask' now checks that the entered symbol exists, a fix for the end-of-entry checking when extracting documentation from the info file, and a start on adding some indentation hints for newer additions to rep (e.g., things like `define' and `letrec').
Addition of sawmill-interaction-mode, sawmill-eval-defun, and sawmill-eval-expression, and fixes to make keybindings (C-j, C-M-x, and M-:) work correctly.
The apropos functions will now attempt to get a description from the sawmill and rep info files if a symbol has no doc-string, and general tidying up of the code.
