PHYSFS_setWriteDir() broken in PhysFS 1.0.1

[Dennis Schridde]

Hi!
PHYSFS_setWriteDir() seems broken in PhysFS 1.0.1.
In the documentation it says:
---
Set a new write dir. This will override the previous setting. If the directory 
or a parent directory doesn't exist in the physical filesystem, PhysicsFS 
will attempt to create them as needed.
---
But this call will fail with an "File not found" error, if the specified write 
dir does not exist.
This can be confirmed on several distributions and also with physfs-1.0.0

My idea: Either adjust the docs, or fix the code and create a new bugfix 
release.

Thanks for your support,
Dennis
