Let me improve on that.  That it _can_ be done doesn't mean that it
_should_ be done, but we can decide on that.  There are various levels
to this integration:

0. no integration

1. This is the current integration.  I.e. when C-h o is pressed on the
   symbol the global name is discovered and used as the default.  This
   is how SLIME work with CL's namespacing system.  SLIME is a very well
   tested and widely appreciated Common Lisp IDE for Emcas.

2. The shorthands from the buffer where the minibuffer was entered are
   _not_ in the completions list, but typing one of them interns the
   symbol with those shorthands present, so you get the desired result.
   This would fix Phil's visually-copy-and-type scenario.

3. (Eli's suggestion): the completion list would be augmented with the
   shorthands from the buffer where the minibuffer was entered from.

In levels 2 and 3 the user might be surprised that what once worked for
one 'C-h o' session no longer works for another 'C-h o' session.  The
only way I can see this being acceptable is if the user is somehow made
aware -- visually or otherwise -- that the list she is seeing is somehow
connected to the origin buffer.

In contrast, C-M-i (where level 3 happens) never really leaves the
buffer: its results are connected to it because they will be inserted
there.
