Maintenance proposals for Emacs package

[nealsid]

Hello,

I'm a new OpenIndiana user and Emacs user. I thought some changes to the Emacs package might be helpful, which I'd be happy to submit a patch for:

• Update the README, especially w.r.t. the list of patches being applied
• I was also wondering if there is any particular reason the find-program variable value is patched at compile time rather than relying on runtime configuration via Elisp (see https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/editor/emacs/patches/01-find.patch). It would help both minimize the number of patches as well as improve the out of the box experience to set find-program, as well as Man-sed-command and insert-directory-program, to their GNU variants inside site-start.el as part of the package installation.

Thanks!
