git-clean: implement partial matching for selection

Browse source 
Document for interactive git-clean says: "You also could say `c` or
`clean` above as long as the choice is unique". But it's not true,
because only hotkey `c` and full match (`clean`) could work.

Implement partial matching via find_unique function to make the
document right.
