c:\go\src>go test -v -run=TestExecutableGOROOT cmd/go

What did you expect to see?

I expect test to PASS.

What did you see instead?

=== RUN   TestExecutableGOROOT
--- FAIL: TestExecutableGOROOT (0.20s)
        go_test.go:3986: C:\Users\brainman\AppData\Local\Temp\1\gotest650109735\newgoroot\bin\go.exe env GOROOT = "c:\\go", want "C:\\go"
FAIL
exit status 1
FAIL    cmd/go  5.226s

I suspect this fails because my GOROOT drive letter is small ("c"), but the test expect it to be big ("C"). I think we should adjust the test to allow for either.
