Title: Add a space between the command and the args

When specifying --args="arg" on the command line it gets appended directly to the cmd string which gets passed to the system() call and you end up with:

HipHop Notice: File could not be loaded: /path/file.phparg

That means you always have to use --args=" arg" which I find silly. (untested, but it looks right)
