The problem is running test-config inside of a git alias. The
bin-wrappers will set the exec-path to the root-level of git's build
directory, which the git binary will then stick at the front of the
$PATH.

So the simplest solution really is: don't do that. The only debate in my
mind is whether this is rare enough that it won't bite somebody again in
the future, or if we should look into a solution that makes this Just
Work.
