It strikes me that I've seen code somewhere that uses slurs instead of
brackets.  I find this:
http://www.lilypondforum.de/index.php?topic=1658.0

The results look great, but of course, the slur is broken.  It might
not be hard to modify that routine to do what you want..

How are you duplicating the other example, with an unbroken bracket?
If you displace the TupletNumber in an ordinary bracket, the gap will
remain.

Is the bracket notation fairly common?  I've certainly seen the
slur-above notation.

I'm asking because it might be fairly easy to modify the C++
TupletBracket stencil code to produce such slurs based on a context
property.

 Also, a full bracket might be used if the tuplet number wouldn't
intersect the bracket.  Maybe this should be default behavior?  I know
I've seen the bracket notation in Britten, albeit without the tuplet
number.
