The gpm-1.19.3-16 rpm includes the files t-mouse.el and t-mouse.elc in /usr/share/emacs/site-lisp. As far as I can tell, these are emacs only files. Therefore, they should be included in the emacs rpm or in an emacs-gpm rpm. Sorry if there's a bunch of blank lines after this. I am entering this from lynx.
these files are harmless, and tiny. They don't hurt anything by being on a system that doesn't have emacs. It makes very little sense to break them into a subpackage, or move them to another package. The gains are simply not great enough.
