formatting issues

[Werner LEMBERG]

I'm improving the texinfo documents to get a decent layout (no
overlong lines any more for lilypond.dvi!).  Some remarks:

  . Don't use extra indentation within @example ... @end example.

  . Please use `@/' to insert breakpoints in long file names, namely
    after `/' but before `-' and `.':

       http://www
       .foo/
       bar
       -line.ly

    This makes it clear that `.' and `-' are part of the file name and
    not sentence syntax.

    If you disagree please tell me, and I'll change it accordingly.
