[Smaug] A quick scripting puzzle

[Peter Belew]

That one doesn't work all the time. Try

   cal 10 2005 |  tail -2 | head -c2

You get the Sunday before the last one. 'cal' outputs a constant
number of  lines, so there is variable padding at the bottom.
I took care of that in my implementation, to be published
publicly after I see a few more responses.

BTW if you try

  cal 9 1752

you'll see even more blank lines. :) We can thank Lord
Chesterfield for that one (as well as Pope Gregory et al.)

(BTW thanks to James for suggesting the trick that solved that one
in my solution).
