I worry that changing the arguments list of such a generic function
in Emacs causes further confusion.  For instance, since Gnus supports
Emacs 21, 22, 23 and XEmacs, source codes that use `pop-to-buffer'
and need to use the NORECORD argument will have to get more complicated.
We might, if anything, give up using that argument, since it doesn't
seem to be very important in the codes in question actually.  It also
might suggest that such arguments that are not indispensable and are
incompatible with versions of Emacsen will be doomed to be not used.
So, I think we have nothing to do for `pop-to-buffer'.
