[parted-devel] [PATCH] parted: restore partition_print

[Wang Dong]

The function partition_print is used to print out some
basic information of a partition. It was implemented
in v1.8 but ripped out later.

Compared with the old version of this function, some changes
are introduced to restore it.
1. ped_file_system_probe persede ped_file_system_open and
   ped_file_system_close to get the file system type.
2. the file system resizing part is removed.
