[Qemu-devel] [PATCH v4 1/6] qemu-io: Add missing option documentation

[Eric Blake <eblake@redhat.com>]

Commit 499afa2 added --image-opts, but forgot to document it in
--help.  Likewise for commit 9e8f183 and -d/--discard.

Finally, commit 10d9d75 removed -g/--growable, but forgot to
cull it from the valid short options.
