Yep, that works fine.  When I

cp pythondemos.py pytest
./pytest -dev tk

The plotting works fine and the name (pytest) is displayed properly with
the new python interface.

To close off the possibility this was python specific I also did this test.

cp x08c test.x08c
./test.x08c -dev tk

and that invoked the same error.

I checked that that the correct argv string was being passed to the python
version of plParseOpts.  It is possible the "le" name result we were getting
for the old python interface was due to some problem with the python wrapper
for plParseOpts, but I haven't investigated further for that situation with
the pytest name. But apparently that is not a problem for the new python
interface since it delivers the name pytest without a problem.

So I guess the only remaining question is how can you change the underlying
code so that invoking program names with a "." in them (such as in the above
C code test and also in the original python example) are acceptable to the
tk driver.
