    Remedy ineffective backslashes and fix regexps
    
    * lisp/info.el (Info-read-node-name-2): Double backslash for intended
    escaping effect.
    * lisp/term.el (term-send-function-key): Remove redundant `+`.
    * lisp/leim/quail/indian.el:
    * lisp/simple.el (scratch-buffer, get-scratch-buffer-create):
    Remove ineffective backslashes.
