[libvirt] [PATCH 0/2] virsh: improve option parsing, including a regression fix

[Eric Blake]

I wish I could have come up with something with fewer lines of code
changed; but I'm at least happy that the end result only touched
vshCommandParse and its helper functions rather than having to touch
lots of existing commands.

This fixes multiple bugs: a regression in 'virsh freecell 0' parsing,
as well as an infelicity in 'virsh vol-create --pool default vol.xml'
handling.  It also makes it so that 'virsh vol-info vol-name pool-name'
works without having to specify an explicit --pool argument.

Eric Blake (2):
  virsh: list required options first
  virsh: fix regression in parsing optional integer
