[pve-devel] [PATCH common] format: fix render_bytes with CLIFormatter

[Stefan Reiter <s.reiter@proxmox.com>]

CLIFormatter passes in an options hash as a second paramter, which so
far was ignored. Now that we treat it as a precision parameter, check if
it is a hash and extract the option from it before using it.

Otherwise perl puts HASH(0x...) into the format and sprintf chokes.
