commands fail on win32 if the %COMSPEC% env variable is defined with arguments

[ramaboule]

In my case, I had %COMSPEC% defined as:

%SystemRoot%\system32\cmd.exe /E:32768

And the my win32 slave kept failing to launch any commands. Please see the commands.py patch attached that fixes my issue. There may be a more elegant way to do it though...

PS The version I was running is 0.7.7 but the Version combo box on trac does not give me this option PPS I made the patch using a fresh pull of the HEAD with darcs
