[libvirt] [PATCH] virsh: Honor reedit opts printing to a function



When printing reedit options we make stdin raw. However,
this results in stdout being raw as well. Therefore we need
to return carriage when doing new line. Unfortunately,
'\r' cannot be part of internationalized messages hence
we must move them to formatting string which then in turn
become huge and disarranged. To solve this, a new function
is introduced which takes variable string arguments and
prepend each with "\r\n" just before printing.
