doc buglets

[Karl Berry]

Some very minor points in the lilypond doc:

1) GhostScript is spelled with a capital S.  I am pretty sure the
official spelling is lowercase s, simply Ghostscript.

2) The `Tablatures' section starts with `Tablature notation is used
   music for ...'.  This is missing a preposition, it should be `used
   for music' or `used in music' or some such.

3) The copyright only goes through 2001, but it's 2002 now :).  Also,
   I'm sorry to say that copyrights are really supposed to list every
   year individually (1996, 1997, 1998, 1999, 2000, 2001, 2002).  Ugh.


Thanks for Lilypond.  Many years ago I typeset a book with music 30-odd
pages of music examples using a (heavily) customized version of
MusicTeX.  I was amazed at what MusicTeX could do, but I am a hundred
times more amazed at Lilypond :).
