Hmmm... it looks like my go generate ./... code is breaking the tests... sorry about that @derekjobst - let me investigate.

[derekjobst]

I got caught up on Stringify returning a string with the empty Permissions{} in it when Team is converted to a string.

This was easy to fix in strings_test, but the auto-generated github-stringify tests for TestTeam_String refer to a parent team, which does not include the empty Permissions in the string.

It seems like the best solution might be to have the stringifyValue function in strings.go omit empty Permissions.

[derekjobst]

I've reverted the pointer change to get tests passing — happy to change back if we'd like to change the stringify methods

OK, excellent. I've gone ahead and created #1865 and #1866 to address this.

Thank you, @derekjobst !
LGTM.

@gmlewis do you know when we might be able to get this into a release? It looks like there are a few other changes since the last one :)
