[TIP/TRICK] a function to shift a tuplet

[Kieren MacMillan]

Hello, all --

Sometimes (though not very often!), Lilypond puts a tuplet in the  
wrong place, and you need to shift it up or down (or, I suppose, left  
and right!?).

Since it actually requires two shifts -- one each for the  
TupletBracket and TupletNumber -- I've written a simple function to  
encapsulate the whole tweak.
The function and an example is included, below.

Enjoy!
Kieren.

2 spaces
	\times 2/3 { c4 c c }  % \once in the function means subsequent  
tuplets 'revert'
