    Add a scratch buffer to the history ring. (closes #3082) · 99468835
    Kevin J. McCarthy authored
    This patch creates an extra slot in the history ring for a scratch
    buffer (at h->last).  If you are editing inside that buffer, it is
    preserved when you scroll up/down through the history.  Editing while in
    other places in history are *not* preserved with this patch.
    Another behavior change worth noting with this patch: the position in
    history is now reset to the scratch buffer after each input entry.
    Before, the position would be stay wherever it was - you didn't restart
    at the "bottom" each time.
