Thanks for the reminder... I remember you had already posted it, lazy me!
It's quite nice, even if you always have to specify the number of 
strings even for the default barré (6 strings).

Can it be adapted to this function?
http://lists.gnu.org/archive/html/lilypond-user/2012-12/msg00825.html

I see that $strg must be replaced by $fretnum, but I don't know how to 
handle ly:music? and $music.

BTW, what about including one of these snippets in the Documentation?
Specifically here:

I'm going to add a comment to issue 3056
