Before introducing interactive git-clean, refactor git-clean operations
into two phases:
* hold cleaning items in del_list,
* and remove them in a separate loop at the end.
We will introduce interactive git-clean between the two phases. The
interactive git-clean will show what would be done and must confirm
before do real cleaning.
