[ditz-talk] I don't have all the same environment variables as you

[Harold Hausman]

Hi,

Ditz is awesome. It hits on all the levels I like. Congratulations are
in order. :)

However, ditz makes some assumptions about environment variables that
make it fail not-so-gracefully on some of my machines. (Their
operating systems to remain nameless to protect the otherwise
innocent.)

Something like the following patch might (it's not tested extensively,
or at all really) save some users some trouble.

Thanks for ditz, I'm really enjoying using it.

Regards,
-Harold
