Option -h added to iostat. This option makes the device utilization
report easier to read with long device names.

Subject: feature request: Resizing device column in iostat to size of larges lvm device name

Hello,
I'm sending three patches against sysstat-10.0.0:
* sysstat_1.patch
  adds -h (human readable) option to iostat tool (just to indent the row after the device name)
[...]

If you need a clarification to arbitrary of them please sent me an e-mail.

As far as reports go this is rather hard to read.  Can we get the Device column
to size based on the longest name?
