    patch 9.0.1126: bracketed paste can be enabled when it is not recognized

    Problem:    Bracketed paste can be enabled when pasted text is not recognized.
    Solution:   Output t_BE only when t_PS and t_PE are set.

+sure that bracketed paste is not enabled when the escape codes surrounding
+pasted text cannot be recognized.

 If your terminal supports bracketed paste, but the options are not set
