bug#9125: eval-after-load docstring precision

[jidanni]

This language is not precise enough:

    eval-after-load is a compiled Lisp function in `subr.el'.

    (eval-after-load FILE FORM)

    Arrange that, if FILE is ever loaded, FORM will be run at that time.
    If FILE is already loaded, evaluate FORM right now.


'FORM will be run AT that time.'
So the function would be called eval-at-load... sort of like "meet you
at the party" what ever that means order-wise.

So the line should say:
    Arrange that, if FILE is ever loaded, FORM will be run *immediately 
afterward*.
