[Qemu-devel] [PATCH] block: fix qemu-img --help invocation

[Jeff Cody]

This fixes a bug introduced in commit ac1307ab, that caused the
'--help' option to not be recognized as a valid command, and not
print any help.

This also restores the previous behavior of qemu-img printing the full
help when called with no arguments.
