Command line interfaces should use dash, not underscore, as many keyboard layouts allow that to be typed with fewer shift key presses. Also, the US spelling of --tunneled gets more google hits than the UK spelling of --tunnelled. * tools/virsh.c (opts_migrate): Allow US variant. (opts_blkdeviotune): Prefer - over _. * tools/virsh.pod (blkdeviotune): Fix spelling.
