I agree. Didn't you even make a patch for this that we didn't merge
because we didn't have a use case?

(I have a memory problem, admittedly, too much people and patches
flying around ...)

If you rebase the patch that make it possible to simply name lines
without hogging them, I'm certainly game for merging it.

Enclosing a lsgpio sample output gives extra points.
