What does 'go version' print?

go version go1.3.3 windows/386

What steps reproduce the problem?
If possible, include a link to a program on play.golang.org.

1. Copy https://gist.github.com/nobeans/1fcc22ea9268746455b0 to your local machine like
test-run-bat.go.
2. Create C:\\DIR WITH SPACES\\test.bat with a content like "echo Hello"
3. Run this script `go run test-run-bat.go`

What happened?

An unexpected error occurs to run a BAT file under a path having a white-space only when
specifying a blank argument.
The error message is like this:

'C:\DIR' is not recognized as an internal or external command,
operable program or batch file.

What should have happened instead?

It should be able to run successfully as running a exe file.

Please provide any additional information below.

It doesn't occur without a blank argument even for a BAT file in Windows.
It doesn't occur with/without a blank argument for a EXE file in Windows.
And it doesn't occur with any arguments in Mac and Linux.

Comment 2:

I think, that is how windows cmd.exe works. I did this:
C:\>cmd /c "C:\DIR WITH SPACES\test.bat"
C:\>echo Hello
Hello
C:\>cmd /c "C:\DIR WITH SPACES\test.bat" ""
'C:\DIR' is not recognized as an internal or external command,
operable program or batch file.
C:\>
which looks similar to what you see in your program.
I agree, it is inconsistent, but I think we should let Windows make rules here.

Problem exists also for the exec.go module for starting a process on windows. If you intend to support the windows plattform than this needs to be fixed.
And you are right: Windows make the rule as the Linux guys do and we try to follow...
