links in LSR snippets

[Werner LEMBERG]

LSR files sometimes refer to the manual.  Example:

  makam-example.ly:

   (see the `Learning Manual @version{}, 4.6.3 Other sources of
   information' for the location of this file)

Such references to absolute section numbers are error-prone;
additionally, there is no proper hyperlink.  Any idea how to do
better?
