[parted-devel] [PATCH 2/4] parted: print disk flags

[bcl at redhat.com]

This adds a 'Disk Flags:' line the displays the active disk flags.
In machine mode this is appended to the disk info line, after the
device model.

* parted/parted.c (disk_print_flags): New function
(_print_disk_info): Add Disk Flags information.
