Subject: xl: fixup command line handling for several commands.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~9851
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=0c49cf7d494fc4e9b54a1d7a6ed03a09c01c3eae;p=xen.git

xl: fixup command line handling for several commands.

def_getopt already checks for a minimum number of arguments for us.

"xl save" simply need to use the correct argument for that value,
contrary to the change I made in 23876:b113d626cfaf

"xl block-list" does not need to check for at least 2 arguments, since
it's already been done by def_getopt.

"xl network-list" would previous accept zero arguments and just print
the table header. Insist on a domain argument.
