Agreed. Except that let-binding auto-compression-mode doesn't do much
if anything. Better just check whether auto-compression-mode is nil and if
so don't try to load the .gz file.
Actually, jka-compr.el should provide a list of extensions it understands,
so we wouldn't have to hard-code .gz here. I guess jka-compr-load-suffixes
could be used for that. The code in info.el that handles compressed files
could/should also be merged in.
