Grrr... I should have fixed that a long time ago...

I kept trying to specify the function in terms of Postcondition, and
kept getting myself tied up in knots.

Here is a new spec rewritten as an Effects clause:

* Any existing extension() is removed from the stored path, then
* iff new_extension is not empty and does not begin with a dot
character, a dot character is appended to the stored path, then
* new_extension is appended to the stored path.

That seem clearer to me than the previous wording, and corrects the
missing removal of any existing extension(). Does it look OK to you?

I'm working on test cases now, and will commit as soon as they are
done and passing.
