Show what would be done and a confirmation dialog before actually
cleaning. In the confirmation dialog, the user can input a space
separated prefix list, and each clean candidate that matches with
one of prefix, will be excluded from cleaning. When the user feels
it's OK, press ENTER to start cleaning. If the user wants to cancel
the whole cleaning, simply input ctrl-c in the confirmation dialog.
