When using wildcards as arguments to the processes being spawned by
Popen, it seems to interpret them as hard literals.

IE, when doing something like:
>>> import subprocess
>>> output = subprocess.Popen(['ls', '*'],
stdout=subprocess.PIPE).communicate()[0]
ls: *: No such file or directory
>>>

The default for Popen objects is to not use the shell, thus
no expansion. Set shell=True in the Popen call:

>> import subprocess
>> output = subprocess.Popen(['ls', '*'])
>> ls: *: No such file or directory

>> output = subprocess.Popen(['ls', '*'], shell=True)
>> configure.out svn-stat.out svn-update.out
