Actually I also like that, but if we head down this direction, then why
not go all the way and print a warning on executing autoscr?  Thinking
about it (and reflecting on how I interact with U-Boot), I fear that
even the help message will not get too much attention from people who
should get aware of the problem.

What do other people think about this?

Cheers

If you know why this number is perfect - you're probably a mathematician...
