Junio noticed that switching on autosetupmerge unilaterally started
cluttering the config for local branches. That is not the original
intention of branch.autosetupmerge, which was meant purely for
convenience when branching off of remote branches, but that semantics
got lost somewhere.
If you still want that "new" behavior, you can switch
branch.autosetupmerge to the value "all". Otherwise, it is interpreted
as a boolean, which triggers setting up defaults _only_ when branching
off of a remote branch, i.e. the originally intended behavior.

That is certainly unexpected and unwelcomed. Alas, I think it is
one of the consequences of rarely executed (and thus, tested)
code.
I rarely branch, but use one long running branch to commit and
revert, so that a "git log -S<keyword> -p" brings me back my huge
debug output changes, and therefore I did not catch it.

Me, neither. Therefore, this patch does not change the semantics
of that one. But it was really unexpected for me to see that this
works with anything but remote branches.

Well, I marked it as RFC, and was surprised to wake up to it being
applied. But thanks for not reverting right away; I think this
patch should fix the issue.
