Short abbreviated hash completion or direct use

Hello !

Love Kopia ^^

As in git, I wish I could input only a part of the hash in command line. Indeed, most of the time (kopia policies, kopia ID, don’t (never) collide ).

When there is no ambiguity it should be possible to use a random sub-interval of consecutive chars of the hash (not necessarily from the beginning) . That enables very quick copy/paste with the mouse grabbing a suite of chars from the hash prompted.

Also, one should be able to do completion of hashes. 99% of the times this is 1 or 2 TAB press.

Thanks for the killer app
