Marcel Moolenaar c7c8cf8b2e o Include <sys/uuid.h>. This avoids that applications such as
gpt(8) have to include both <sys/uuid.h> and <uuid.h> only
   because they include <sys/gpt.h> before <uuid.h>.
o  Drop the triple bang in the unicode comment in favor of
   adding '-16' to make it explicit that the unicode characters
   are 16-bit. The fact that we use short as the type of the
   array does give it away; but only to the careful reader.
