ijoin depends on matching column order

When the column order doesn't match, ijoin returns zero rows.

 set v [view {A B C} def {a c d a e f e c d a d e}]
 set w [view {B C D} def {c d e c d f d e f}]
 view $v ijoin $w | dump

 view $v colmap {C A B} | ijoin $w | dump ;# <== zero rows in result

Summary

Oooh, that was a tricky one. Affected "join" vop as well. Fixed in Darcs.
