Agreed.  And glad I brought this planned change up on the list; I have
already got two good suggestions for things that I should have thought
by myself -- but alas, I didn't.  So, thanks guys!

Before proceeding with an attempted implementation in the next days, I
will prepare a brief summary of this discussion in the PLANS directory
(and post it on the list for reference).

In the meantime, of course, further feedback or suggestions are very
welcome.

Thanks,
  Stefano
