another minor quibble: Lilypond really isn't supported on UNIX; Linux and MacOS, not UNIX

[Kenneth Wolcott]

HI;

  This is just a tiny quibble, but the Lilypond Download web page
implies support for UNIX (which implies, at least to me,
SunOS/Solaris, HP-UX, IBM/AIX, etc), where Linux really isn't UNIX.

  See attached screenshot.

Thanks,
Ken Wolcott
