Remove outdated docstring chunk
Tweak more debugging
Set 'true' defaults for run() args.

If this is not done, env var loading won't see these.
Test + impl preserving new Config attr
Failing test re: executor defaults merge corner case
Merge, not update
Use more lenient mock call test semantics.

Required now that we're passing all kwargs into run()
due to merge
Update high level run.echo test
Flesh out that test even more, fix brainos
Forgot to add fixtures
Move comment
Tighten up common test contextmanager use
Update docs re: true lowest level hierarchy items
Shitty update to fix context cloning in internal tasks file
Failing test re: tasks.dedupe setting
Update Config tests to expose new level. Sigh.
