Subject: [PATCH] Do the right thing with empty directory path.

When we convert a file that's in our CWD, on Unix the folder component
of the path will simply be "", whereas opendir() wants ".".

I want to take another more substantial pass at texture resolution, once
we're out of urgent bugfix mode.
