Subject: [PATCH] When recursively creating a directory, make sure the path is
 a directory

The function to recursively create a temporary directory was succeeding if
the requested path existed even though the path was not a directory. Sarg
was then failing with a somewhat unrelated error.

Now, an error message is reported if the path to create exists and is not
a directory.
