Yes, all other Makefile dependencies are written like this.  It's a typo
in "cmDependsFortran.cxx" which uses SHELL escapes instead of MAKEFILE
escapes.  There is actually a test for this that runs with a space in
the path, but it passes because the module path in the test appears
below the build tree and is thus converted to a space-free relative
path.

The commit below fixes the problem and enhances our test to cover the
case.
