PATCH: extra loop tests

[Peter Stephenson <pws@xxxxxxx>]

Tests for the enhanced `for' syntax as well as `select' which is now
testable (according to `cvs annotate', I fixed it all of three years ago,
except as we know it was broken for a large fraction of that time
because of the for-loop change.  A year is a short time in zsh
development).

Extra tests gratefully received, as Felix reminded us, particularly for
interactive stuff (zle, completion) which I will not be attempting
myself.

When we finally get the multiple defined limits problem fixed, I will
produce a test version of 4.1.1.  If tests continue to trickle in, so
much the better.
