Yes, but (once I look at doing it, if it is reasonable to implement)
making "local LINENO" in the function cause local line numbering instead.

The alternative would be an option set before the function is defined
(which I have implemented already, and works).

Of we could have both, perhaps (the option is really cheap, don't know
about the other yet.)

Or of course, we can just pick one way (like everyone else does - though
they haven't all picked the same way) and do that all the time.
