when I was writing the "double" function, I was heavily improvising because
I didn't yet know the \overlay command (or it was not available in older
LilyPond versions). 

A more reliable way would now be: 

% ----------------------------------------------------------------
#(define-markup-command (double layout props letter)
   (markup?)
   (interpret-markup layout props
     #{
       \markup{
         \overlay {
           $letter
           \translate-scaled #'(0.4 . -0.4)
           $letter
         }
       }
     #}))
% ----------------------------------------------------------------

The pair of numbers after \translate-scaled exactly defines the shift of the
additional letter. 
If you don't want additional parameters for the "\double" function, maybe
the use of properties might be an option: 
http://lilypond.org/doc/v2.18/Documentation/extending-big-page#on-properties

I never tried that, but it looks interesting. 
Does that help? 

Cheers, 
Klaus
