snippets -> git no verbatim

[Graham Percival]

Hi John,

Recent changes to LSR .ly export result in many files lacking a
% begin verbatim
Could you have a look at it?

For that matter, I suppose that this is a good time to update the NR 2
snippet lists to match the renamed sections.  Could you modify the
relevant scripts accordingly?


Valentin: given all the problems that the LSR change has caused, how
about we let John handle the next update (ie working out all these
things), and then you start doing it in a week or so.

Cheers,
- Graham
