I have added a couple of unit tests to the suite, describing the two 
functions I added.  I have no unexpectedly failing tests now.

I'm explicitly cc-ing Eric Schulte because he's in the header for 
org-plot.el, and —missing the unit tests for that source— I hope he can 
assist me not breaking what he wrote.  … I guess I can write also test 
cases for what already exists, but I will very likely need assistance.

best regards,
Mario Frasca
