No. There's one other crucial difference here.

This is a list of strings.

This is one string (arguably in a list, but a single string nontheless).
So while the first is passed to the process without change and fails, because 
as explained previously, cd needs a shell, which is not created on a list of 
arguments, the second one is treated like the "one string" case, and 
ShellCommand spawns a shell to execute the command in. I'm pretty sure that 
single or double quotes don't make any difference if you preserve the number 
of arguments.

Cheers,
Kai
