Oh yes, I used file-name-nondirectory instead of file-name-directory,
and forgot the customization documentation.  Here's updated version.

Subject: [PATCH] adding :eps header argument to ditaa code blocks

Use of this header argument will change the back-end engine from
ditaa.jar to a combination of DitaaEps.jar and epstopdf.

This patch is based off of ob-ditaa-eps.el sent to the mailing list by
Arne Babenhauserheide (IMK).
