Add '--bisect' revision machinery argument
From: Linus Torvalds <torvalds@linux-foundation.org>

I personally use "git bisect visualize" all the time when I bisect, but it turns out that that is not a very flexible model. Sometimes I want to do bisection based on all commits (no pathname limiting), but then visualize the current bisection tree with just a few pathnames because I _suspect_ those pathnames are involved in the problem but am not totally sure about them. And at other times, I want to use other revision parsing logic, none of which is available with "git bisect visualize". So this adds "--bisect" as a revision parsing argument, and as a result it just works with all the normal logging tools. So now I can just do gitk --bisect --simplify-by-decoration filename-here etc. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> --- builtin-rev-parse.c | 11 +++++++++++ revision.c | 18 +++++++++++++++++- 2 files changed, 28 insertions(+), 1 deletions(-)
