[XeTeX] vertically aligned sub and superscript

[John Was]

Hmm.

I would just have  enclosed the third element in a \llap{} command!  But 
certainly specifying a new control sequence to cover all three is a good 
idea if this is a recurrent requirement - that way you can tinker with the 
definition of the control sequence until it's just right, then all examples 
will be adjusted accordingly.
