Well, yeah for really quick vi-like... but mostly No, not what I was
after... Even there, my .emacs has settings I want in force, such as
custom fontlocking, etc.. and several `skeletons' I use quite a bit.
(Especially when editing configs) Probably quite a few more that would
not be there with -q but don't involve `requiring' extra pkgs.
Particularly one skeleton that wraps original lines with:
# [HP 10/02/26_14:13:11
# original stuff here
Type my new stuff here
# ]
So I can see exactly what was there and what is new for debug
purposes.

But then I'd miss the joy of doing complicated edits with ed... hehe.
