python build scripts don't escape paths on Windows

[aardappel]

Running with "-d @ -r" on Windows, I get the output:

BUILD SUCCESSFUL
Total time: 4 seconds
Subprocess returned 1
Traceback (most recent call last):
  File "build_all_android.py", line 212, in <module>
    sys.exit(main())
  File "build_all_android.py", line 171, in main
    adb_devices = [d.serial for d in env.get_adb_devices()]
  File "C:\w\lobster\dev\android\buildutil\android.py", line 1182, in get_adb_devices
    capture=True, shell=True)[0]
  File "C:\w\lobster\dev\android\buildutil\common.py", line 470, in run_subprocess
    raise SubCommandError(argv, process.returncode, stderr)
buildutil.common.SubCommandError: Error 1 running C as: C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe devices -l, stderr: {'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
}

Appears it should be quoting paths somewhere.
