This is an enhancement request.  It is a follow-up to bug #10144.

The current behavior of `switch-to-buffer' makes it raise an error if
the selected window is dedicated.  Please provide a user option that
lets you get either this raise-an-error behavior or simply switch to the
buffer in another window (i.e., `switch-to-buffer-other-window'), when
the selected window is dedicated.

IMO, the default behavior (via the default value of the user option)
should switch to the buffer in another window.  I expect that is what is
most useful to most users most of the time.  FWIW, my own code has done
this for decades, and I have never encountered any problem with it.

Note that the use-another-window behavior means that when the selected
window is dedicated, optional arg FORCE-SAME-WINDOW woudl have no
effect.

Note too that this option would affect only the behavior for dedicated
windows.  The error "Cannot switch buffers in a minibuffer window"
would still be raised, if arg FORCE-SAME-WINDOW is non-nil.  It is
only the error "Cannot switch buffers in a dedicated window" that
would not be raised when the option value is non-nil and the selected
window cannot be used.

IOW, this option lets users choose to distinguish attempts to switch
buffers in the minibuffer from attempts to switch in a dedicated window.
That's good - the two contexts are very different.
