Huh. Next time, Chris, search the web before you post. Via a
StackOverflow post, learned about distutils.spawn.find_executable().

Python 2.7.4 (default, Apr  6 2013, 19:54:46) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import distutils.spawn
>>> distutils.spawn.find_executable("python")
'C:\\Program Files\\LilyPond\\usr\\bin\\python.exe'

So that would be the way to go. Render the short-form into an
executable name, then skip the shell.
