[Pythonmac-SIG] Safe way to launch command-line app from python?

[Joachim Mårtensson]

Hello
I want to launch emacs/vi from within python (Pyobjc to be more 
specific), and I want the editor to open a file. however I do not have 
complete control over which file will be launched (the user chooses from 
a tableview), since filenames can contain all kinds of charachters I am 
a little worried over how to accomplish this in a safe way.
Any suggestions?

Thanks in Advance.
