[PATCH 0/3] adding new branch.autosetupmerge option "simple"

This commit introduces a new option to the branch.autosetupmerge setting, "simple", which is intended to be consistent with and complementary to the push.default "simple" option.

The push.defaut option "simple" helps produce predictable/understandable behavior for beginners, where they don't accidentally push to the "wrong" branch in centralized workflows. If they create a local branch with a different name and then try to do a plain push, it will helpfully fail and explain why.

However, such users can often find themselves confused by the behavior of git after they first branch, and before they push. At that stage, their upstream tracking branch is the original remote branch, and pull (for example) behaves very differently to how it later does when they create their own same-name remote branch.

This new option (with push.default set to simple) ensures that push/pull behavior is generally consistent - tracking will be automatically set up for branches that push will work for (and pull will be consistent for) only.
