git-clean: add select by numbers interactive action
Draw a multiple choice menu using `list_and_choose` to select items to be deleted by numbers. User can input: * 1,5-7 : select 1,5,6,7 items to be deleted * * : select all items to be deleted * -* : unselect all, nothing will be deleted * : (empty) finish selecting, and return back to main menu Signed-off-by: Jiang Xin <worldhello.net@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
