That usage message is misleading. You need to use one of -t, -s, -e, -p,
or <type>. So it should perhaps just be:

  git cat-file -t|-s|-e|-p|<type> <sha1>

though that looks terribly ugly. Suggestions welcome.

P.S. Depending on what you're trying to accomplish, "git show <sha1>"
     may be a better choice.
