Problem with padding and TextScript

[Trevor Daniels]

While browsing the Learning Manual I noticed the last example in Section 3.4.4
http://www.lilypond.org/doc/v2.16/Documentation/learning/saving-typing-with-variables-and-functions
displays a fault.  It is intended to show the use of 'padding to displace 
TextScript, but
the script is not displaced.  The example is still incorrect in the latest 
2.17.7 manual,
but I don't know when it went wrong.  Possibly the new skyline code packing 
things
closer together?

I've not yet raised a bug report as I don't know whether this behaviour is now
intended, so I didn't know whether to classify it as a code bug or a 
documentation 
issue.

Comments?
