default padding on TextSpanner

[Graham Percival]

Currently TextSpanner has no #'padding set in scm/define-grobs.scm
Could I set it to 0.8 ?

This example demonstrates how close the edge-text comes to the
staff lines; in the second line demonstrates the more pleasing
look of padding 0.8

Cheers,

\relative c'' {
