[Qemu-block] [PATCH v2 3/3] qemu-img: Document backing options

[Max Reitz]

The create and convert subcommands have shorthands to set the
backing_file and, in the case of create, the backing_fmt options for the
new image. However, they have not been documented so far, which is
remedied by this patch.
