No problem, done as requested. I've attached an updated patch that
takes care to exactly match the trailing whitespace the existing
psql outputs. This fixes most of the changes between observed and
expected test results.

Due to the fact that this patch does alter the output for newlines
and wrapped lines (being its intent), the patch does alter expected
testcase output for these specific cases. Because the old
wrap/newline code put ":" and ";" in place of "|" between columns,
this meant that it never worked for the first column of data, which
included single column result sets. This necessitated some changes
to the expected results to reflect this change (which now makes the
output uniform for all columns, irrespective of position).

Regards,
Roger
