Re: [libvirt] [PATCH] virsh: consolidate memtune docs

* tools/virsh.pod (memtune): Drop second copy, fill to 80 columns, enhance wording. --- Seeing memtune twice in the man page is a bit confusing.

This patch doesn't touch the pending issue of whether --min_guarantee makes sense, or should be deleted before it becomes a pre-mature API addition. Also, should memtune be changed to use VSH_OT_INT rather than VSH_OT_STRING? The current 'virsh help memtune' output looks weird: OPTIONS [--domain] <string> domain name, id or uuid --hard_limit <string> Max memory in kilobytes --soft_limit <string> Memory during contention in kilobytes --swap_hard_limit <string> Max swap in kilobytes --min_guarantee <string> Min guaranteed memory in kilobytes
