cmd/go: "import cycle not allowed in test" message shows wrong stack

[rsc]

% cd go/src/internal/godebug
% echo 'package godebug; import _ "testing"' >g_test.go
% go test
# internal/godebug
package internal/godebug
	imports math/rand
	imports testing: import cycle not allowed in test
FAIL	internal/godebug [setup failed]
% 

The error is incorrect (the imports it reports are reversed from reality) and incomplete (it doesn't complete the cycle). It should say something like:

package internal/godebug
	imports testing
	imports math/rand
	imports internal/godebug: import cycle not allowed in test
FAIL	internal/godebug [setup failed]
