API is implemented in virsh and virt-admin. It fixes problems with
table-alignment, makes tables more readable and deals with unicode.
Table however could not be implemented in places, which do use simple
lists, or table implementation would change content of output,
which users might rely on.
If you know about other place where it could be implemented,
let me know.

New subject: [libvirt] [PATCH v2 06/13] virsh: Set up cmdDomblkinfo() and cmdDomblkinfoPrint() for vshTable API implementation
I've moved all the printing from cmdDomblkinfoPrint() to cmdDomblkinfo(),
and renamed the cmdDomblkinfoPrint() to cmdDomblkinfoGet(), since nature of
that function changed from gathering and printing informations only to
gathering information. This I believe simplifies the functions and
makes the implementation of vshTable API simpler.

API is implemented in virsh and virt-admin. It fixes problems with
table-alignment, makes tables more readable and deals with unicode.
Table however could not be implemented in places, which do use simple
lists, or table implementation would change content of output,
which users might rely on.
If you know about other place where it could be implemented,
let me know.
