Surely both FilePath's and command line arguments are sufficiently
string like that a reasonable interpretation of them is String? We
don't want to provide an interface to Unix, we want to provide a
proper abstraction over the underlying details.

It would be a shame if on my Windows box I had to jump through
artificial hoops because Posix is a bit broken...
