The `-use_dirs` option will cause everything to be rendered inside directories. There may still be some problems with it, that need looking into (it doesn't e.g. check for conflicts between foo/index.mdwn and foo.mdwn), but seems to work well enough for me... The patch also improves, I think, the parentlinks code a little, as it uses generic routines to actually find the target location now.
