Re: [libvirt] [PATCH] [BUGFIX][PATCH] send-key: fix scan keycode map

Now, bad key-code in send-key can cause segmentation fault in libvirt.
(example)
  % virsh send-key --codeset win32 12
    error: End of file while reading data: Input/output error

This is caused by overrun at scanning keycode array.

Fix it.

ACK and pushed. Converts an infinite loop back into the intended bounded array scan.
