octave-2.0.13-2.0.13.90.patch.bz2 - malformed patch?

[john]

I am trying to build the latest test release.
While patching octave-2.0.13.tar.bz2 with
octave-2.0.13-2.0.13.90.patch.bz2 I get the error:

(Creating file doc/liboctave/liboctave_18.html...)

Does this imply the patch file is broken, or that my patch program is
broken, or something else. 

My patch program says:

prompt:>  patch --version
Patch version 2.1

The obvious solution for me is to get the newest test release;
but does everyone else suffer from not being able to use
octave-2.0.13-2.0.13.90.patch.bz2?
