Great! I've tested the attached patch and it seems to do the trick.
Let me know if subversion doesn't like the git patch format and I'll
try to redo it in a more subversion friendly way. The git/case-1/
README file was very helpful in setting up and working with a git-svn
clone of the repository, but it doesn't say anything about creating
patches that can be used with subversion.
Thanks,
Dave

Subject: [PATCH] Get default device from PLPLOT_DEV environment var
If a device is not explicitly specified (e.g. via "-dev ..." on the
command line), the device given by the value of the PLPLOT_DEV
environment variable, if defined and non-empty, will be used.
