[SQL] Proposed patch - psql wraps at window width

I've got a patch to psql that offers a "no wider than terminal" option, 
patched against cvs head.  Would anyone be willing to test this before I 
submit the patch?

# \pset format aligned-wrapped
# \pset border 2
# select * from distributors order by did;
Word wrap debug: rows=11 terminal=66 total_w=108

Avg= 2 11 17 0
