On Windows Process.spawn 'command', 'arg1', 'arg2', ... evals the arguments
Environment: ruby 2.0.0p195 (2013-05-14) x64-mingw32 on Windows 7 64bit
According to the Process.spawn documentation, the syntax 'cmdname, arg1, ...' doesn't involve the shell. Indeed, on Unix this is true: ((%Process.spawn 'echo', '$PATH'%)) prints '$PATH'.
But on Windows the behaviour is different: executing ((%Process.spawn 'echo', '%Path%'%)) prints the contents of the Path environment variable.
I think the behaviour should be the same on the different OSes; at least, if it is not possible, the documentation should point it out.
