Code review comment for lp:~themue/juju-core/020-cmd-status-subordinates

Somewhat grudgy LGTM, although I don't like how the tests and
readability are both deteriorating. The output is fine, that's what's
important and both issues above can be fixed in a follow up.

cmd/juju/status.go:182: // prinToSubUnitMap will collect mappings from
principal unit names
readability here really could be improved, but i'm not blocking this for
that.

this is *DEFINITELY WRONG*, yet another copy of exactly the same test
driver function as TestStatusAllFormats and TestRelations. I'll fix this
in a follow up though, not blocking.
