2897 "zpool split" documentation missing from manpage

  Found this option in some Oracle documentation and wanted to check out the
  zpool manpage on it in OI. Unfortunately it seems to be missing from the
  manpage, so I first thought it was unsupported. However, "# zpool split" does
  print the correct usage. Testing with the "-n" switch makes me believe it is
  supported (I don't actually need to split my pool).
