   Second opinion is welcome :-)

Cool.

         (let* (...
                (neo-buf nil)
                (other-buf nil)
                (neo-wnd nil)
                (other-wnd nil)
                (filename nil)
                ...)

You can write these w/o the ‘nil’ and even w/o the per-var
parens.  Conventionally, such vars are grouped at the end of the
‘let’ VARLIST block, e.g.: (let* ((v1 1) (v2 2) v3 v4 v5) ...).

           (when (and neo-buffer
                      (or (eq buf-0 neo-buffer)
                          (eq buf-1 neo-buffer)))

presuming ‘buf-0’ and ‘buf-1’ are never nil, you can use ‘memq’:

 (when (memq neo-buffer (list buf-0 buf-1)) 

This constructs a list and discards it after the ‘memq’ so maybe
not too indicated if gratuitous garbage goes against your grain.

             (progn

This is superfluous; (when (progn ...)) ≡ (when ...) in meaning.
Same goes for the other ‘progn’.
