Actually, I was just testing this, and it doesn't work.

You added these macros:
%define emacsversion v=$(rpm -q --qf=%%{VERSION} emacs) ; case $v in
2*) echo $v ;; *) echo 0 ;; esac

%define xemacsversion v=$(rpm -q --qf=%%{VERSION} xemacs) ; case $v in
2*) echo $v ;; *) echo 0 ;; esac

And so whenthere is a Requires: emacs-common >= %{emacsversion} you
get an error like this:

error: line 21: Dependency tokens must begin with alpha-numeric, '_'
or '/': Requires:  emacs-common >= v=$(rpm -q --qf=%{VERSION} emacs) ;
case $v in 2*) echo $v ;; *) echo 0 ;; esac
