Quickly reading through it, here's a couple.
1) I think cases where install time dependencies on plain "emacs" or "xemacs"
are desirable are very rare. The usual problem with those is that they bind
the add-on packages to the corresponding full featured variants, ie. ones
built with X etc, so one can't use them with only the -nox variant installed.
That's why I addded a virtual "xemacs(bin)" Provides to the xemacs and
xemacs-nox packages - that'd be a better thing to have a dependency on than
eg. "xemacs" unless the full featured GUI version is specifically required.
The emacs packages don't have that functionality (yet?), so I think the best
thing for them for now would be to have a dependency on emacs-common instead
of emacs or emacs-nox.
2) At least in the XEmacs case, the dependency on xemacs(bin) should be
versioned, like "Requires: xemacs(bin) >=
$evr_of_xemacs_used_to_build_the_package". The xemacs-bytecompiled *.elc
files are in the vast majority of cases forwards compatible, but much less
often backwards compatible. See the xemacs-packages-base and
xemacs-packages-extras packages for examples. (Hm, I see those have deps on
xemacs-common instead of xemacs(bin), will have a look.)
