I'm still confused.  Do you mean that C-x b, when it switches to a
buffer previously shown in that window, should not change the ordering
of buffers previously shown in that window?  And behave so if and only
if 'switch-to-prev-buffer-wrap' is non-nil?  Then what would users do if
they (1) want to use your new option but (2) still want C-x b or C-x
C-left make that buffer the most previously used one in that window?
