Log message:
        Extensive changes to support multiple xscheme buffers:
        (run-scheme): Break up into new functions to facilitate starting
        processes in other buffers.
        (xscheme-start, xscheme-read-command-line): New functions.
        (start-scheme, select-scheme)
        (default-xscheme-runlight)
        (global-set-scheme-interaction-buffer)
        (local-set-scheme-interaction-buffer)
        (local-clear-scheme-interaction-buffer)
        (exit-scheme-interaction-mode)
        (verify-xscheme-buffer): New functions.
        (xscheme-process-name, xscheme-buffer-name)
        (xscheme-runlight): New internal vars.
        (default-xscheme-runlight): New const.
        (xscheme-start-process): Add args for the process/buffer names.
        (reset-scheme): Pass process/buffer names.
        (scheme-interaction-mode): Initialize new local vars.
        (reset-scheme, xscheme-send-string-2, xscheme-process-running-p)
        (xscheme-select-process-buffer, xscheme-process-buffer)
        (xscheme-send-region, xscheme-send-char, xscheme-send-interrupt)
        (xscheme-goto-output-point, xscheme-write-message-1): Use new
        var xscheme-process-name.
        (xscheme-start-process): Initialize xscheme-process-name and
        xscheme-buffer-name in the process buffer.  Pass buffer name to
        xscheme-modeline-initialize.
        (xscheme-modeline-initialize): Add argument to specify buffer name
        for mode-line vars.
        (xscheme-process-sentinel): Make sure sentinel is run in the
        process buffer so it sees its local vars.
        (xscheme-process-filter-initialize, xscheme-set-runlight): More
        elaborate logic to handle multiple-buffer mode lines.
        
        (xscheme-enter-input-wait): Re-enable control-G handler upon
        entering input wait.
        
        (scheme-interaction-mode): Add arg to preserve local vars.
        (xscheme-enter-interaction-mode)
        (xscheme-enter-debugger-mode): Preserve local vars.
        (xscheme-start-process): Clobber local vars.
        
        (scheme-interaction-mode-commands): Allow end user to add commands
        to scheme-interaction-mode keymap.
        (scheme-interaction-mode-commands-alist): New variable.
        
        (xscheme-send-string): Don't use insert-before-markers.
        
        Implement a per-buffer kill ring:
        (xscheme-insert-expression)
        (xscheme-rotate-yank-pointer, xscheme-yank)
        (xscheme-yank-pop, xscheme-yank-push): New functions.
        (xscheme-expressions-ring)
        (xscheme-expressions-ring-yank-pointer)
        (xscheme-expressions-ring-max): New variables.
        (xscheme-send-string-1): Call xscheme-insert-expression to save
        expression in ring.
        (xscheme-yank-previous-send): Now an alias for xscheme-yank.
        (xscheme-previous-send): Deleted variable.
        
        (xscheme-send-string-2, xscheme-send-char, xscheme-send-proceed,
        xscheme-send-control-g-interrupt): Use process-send-string rather
        than send-string.
        
        (xscheme-send-region): Insert a newline after an expression that
        is submitted in the interaction buffer, for consistency with
        recent changes to Edwin.
        
        (xscheme-delete-output): New function mimics comint-delete-output.
        (xscheme-last-input-end): New internal variable.
        (xscheme-process-filter-output): Update xscheme-last-input-end.
        
        (xscheme-send-control-g-interrupt): Make sure that
        xscheme-control-g-disabled-p is looked up in the right buffer.
        
        (xscheme-enable-control-g): Clear C-g message if visible.
        (xscheme-control-g-message-string): New internal var.
        (xscheme-send-control-g-interrupt): Use new var.
        
        (xscheme-send-control-g-interrupt, xscheme-send-interrupt): Delay
        after sending interrupt in order to work around race condition.
        
        (xscheme-send-control-g-interrupt, xscheme-send-interrupt)
        (xscheme-send-char): Use xscheme-send-char rather than send-string
        to send single char.
        
        (xscheme-process-filter, xscheme-process-filter-alist): Add
        support for evaluating expressions outside of the call-excursion.
        (xscheme-process-filter:string-action-noexcursion): New func.
        
        (xscheme-write-value): Change output string to match that used by Edwin.
        
        (xscheme-coerce-prompt): Don't write a space after a command
        prompt.  The PROMPT-FOR-COMMAND- procedures will take care of this
        for us.
        
        (reset-scheme): Delete process after killing it.
