If a symbolic link exists pointing to a nonexistent file, an "ln -sf"
command to change that link that defaults the name of the target to
the name of the source will fail with the error "File exists".
For example:
           ln -s xxx yyy      "yyy" points to a nonexistent file.
           ln -sf test/yyy     "test" can be any path.
The second "ln" command should remove "yyy" in the current directory
and recreate it as a symbolic link pointing to "test/yyy".  However,
it does not remove "yyy" and instead fails with the error "File exists".
