Subject: [PATCH 72/75] parted/ui: remove unneccesary information of command

 line

When some command fails, the information still exists in

command_line buffer. When in command mode or interactive mode,

if an interactive exception prompts, the remained information

will be processed as option from user. This will raise some other

information or even unexpected results. So before getting option

input from user, clean the command line buffer.

Example: When the disk label is invalid and user tries to make

	 new partition on the device with command like,

	 mkpart 0 50%. Then parted will raise an exception

	 telling an invalid disk label found and whether to correct it.

	 But at this time 0 as the input of mkpart will be

	 considered as the option input for the exception(yes/no).

	 So one more exception will raised with error information.
