Resolve the win32 exec cmd bug, at least as far as some unixes support
  it.  Presume the command contains a filepath and transpose forward
  slashes to backslashes in the path.  (Note part of the bug, correctly
  identified by the poster of 7415, was the /c flag being transposed to \c).

  There has to be a better way, but at least this is now partially, and not
  entirely broken.  Command.com _does_ accept quoted file paths with spaces
  for the executable.
