It seems pretty clear that there has been an oversight in the
implementation of the :cb and :lb commands, even pointed to by the
text of E37. If there is some reason that the :cb and :lb commands
should not be extended to accept !, then the current text of E37 is
inappropriate for that error condition.
Try using the attached patch which enables the "!" modifier for the
":cbuffer" and ":lbuffer" commands.
