Re: switch-to-buffer-other-frame fails to pop-up window

[Mark T. Kennedy]

two observations:

1) contrast the behavior of 'c-x 5 b' with 'c-x 4 b'.  'c-x 4 b' always forces 
the creation of two
different windows, even when displaying the same buffer.  'c-x 5 b' does not 
always force the
creation of two frames.

2) one might guess that 'switch-to-buffer-other-frame' is essentially a wrapper 
that
sets 'pop-up-frames' to 't' and then calls display-buffer (and it is).
while the behavior of display-buffer is meticulously documented, the observed
behavior clashes with the documentation for 'pop-up-frames'.  now if it were
called "maybe-pop-up-frames" or "frequently-pop-up-frames", i wouldn't feel
so bad, but... :-).

so i'm requesting (not demanding :-) a change in behavior.

what use case would clash with a change like this?
