Oh, the funny indentation came back, do you have some Emacs setting
that's doing that?

Oh yeah, that works.  We should try not to add compiler warnings though:

  ELC      net/eww.elc

In toplevel form:
../../emacs-master/lisp/net/eww.el:315:1:Warning: Unused lexical argument
    ‘end’
../../emacs-master/lisp/net/eww.el:315:1:Warning: Unused lexical argument
    ‘beg’

I think we can just drop the arguments as well, lisp programs can always
do (eww (buffer-substring BEG END)) instead.

Do you think the prompt string should be a bit more detailed?  "Query"
seems a bit vague (e.g., consider if you hit M-s M-w by accident).
Maybe we should just do (call-interactively 'eww) and then we'll get the
prompt from there.
