ps_grant.result:
  Fixing result order.
grant.result:
  Adding test case,
  fixing result order.
grant.test:
  Adding test case.
sql_acl.cc:
  Fixed that my_charset_latin1 was incorrectly used instead of system_charset_info.
  This problem was previously fixed by Ingo in 5.0.
  This patch is basically a backport of the same changes into 4.1.
