I like the overall idea, but only for printing all variables.
It's then possible to grep the result to find the one variable one is
interested in.

I've taken that patch in my tree (dropped the per-variable print, and
adapted the printvars a bit), and will send a pull request to Peter
later tonight.

Regards,
Yann E. MORIN.
