[PATCH 0/3] auto-sizing default abbreviation length

So here is what I queued in 'pu' tonight after back and forth with Linus and Peff. The third step from Linus needs to be signed off and also a meaningful log message for it needs to be written, and also may need to be updated to include what Linus did in [*1*], but otherwise I think these are in good enough shape for people to start playing with them.

They apply on top of Peff's jk/ambiguous-short-object-names topic that ends at 5b33cb1fd7 ("get_short_sha1: make default disambiguation configurable", 2016-09-27).
