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). *1* http://public-inbox.org/git/<CA+55aFxyF=xX84AXr8MG14MRHwdrQw00PBM20UfqBdidaeqdMg@xxxxxxxxxxxxxx> Junio C Hamano (2): abbrev: add FALLBACK_DEFAULT_ABBREV to prepare for auto sizing abbrev: prepare for new world order Linus Torvalds (1): abbrev: auto size the default abbreviation builtin/fetch.c | 3 +++ builtin/rev-parse.c | 5 +++-- cache.h | 4 ++++ diff.c | 25 +++++++++++++++++++++++-- environment.c | 2 +- sha1_name.c | 28 +++++++++++++++++++++++++++- transport.h | 3 +-- 7 files changed, 62 insertions(+), 8 deletions(-) -- 2.10.0-622-g05f606bbb0
