Hmm, "newbie protection" doesn't sound good.  It sounds like
"screw the old-timers and let's change well-established workflow".

The expectation is that one always pulls into origin, merges
into master, and maybe checks out master to see the remote
master.  From then on, they decide what, where and how to
merge (from) master into any local branches, and then
eventually export local branches to the public.

The "^branch.\.*" options seem to be counter-intuitive to
1) git's behavor and 2) see above.

Generally "pulling" a remote master in a local branch, without
the local "origin+master" being fast-forwarded/merged should be
considered non-git-conformant behavior.  Assuming that the local
branch is a branch of master/origin, which is almost ever the case.

It should probably have branch.*.remote _and_ branch.*.merge set
for completeness.  Or we should remove the branch.* options
from git-config and leave this up to porcelains.

How does this "set" it?
