It works the same way on XP, at least:
>>> import subprocess
>>> cmd = ['svn', 'ls', '.']
>>> subprocess.call(cmd, shell=False)
svn: '.' is not a working copy
According to the MS docs, CreateProcess works the same way on at least
2K, XP and Vista. The documentation is a bit vague (as usual), but it
contains an example that implies that CreateProcess always adds ".exe"
if not already there, and that you need to use the command interpreter
(that is, shell=True) if you want to run something that's not a Windows
executable module (e.g. a batch file).
