announcing defaults when reading from minibuffer

[Emilio Lopes <eclig@gmx.net>]

I've just asked myself if there's any convention for announcing
defaults when reading from minibuffer.  Skimming the Elisp manual
didn't reveal anything in this regard.  Seaching the archives of this
list I found this message from RMS:

   The standard for Emacs is (default foo).  There may be some
   nonstandard functions that use [foo], due to imperfect quality
   control, but we should stick to the standard (unless we decide to
   change it).

[http://lists.gnu.org/archive/html/emacs-devel/2004-06/msg00085.html]

So I documented this convention in "(elisp) Text from Minibuffer".

Here's the patch:

  If @var{keymap} is non-@code{nil}, that keymap is the local keymap to
