[Qemu-devel] [PATCH 2/2] monitor: support sub commands in auto completion

[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

This patch allow auot completion work normal in sub command case,
"info block [DEVICE]" can auto complete now, by re-enter the completion
function. Also, original "info" is treated as a special case, now it is
treated as a sub command group, global variable info_cmds is not used
any more.
