Please, no.  Users should be able to see the doc
without loading the library.  That's an important
feature, IMO, which has been present from Day One
(or whatever day autoloading was introduced).

I'm all for cosmetic improvements and not having
long lines, believe me.  But I think loading a
library just to (maybe!) change `M-x function-name'
to a key binding description is, I think, misguided.
