Обсуждение: pgsql: Restore psql's former behavior that padding spaces to the right

Log Message:
-----------
Restore psql's former behavior that padding spaces to the right of the last
output column are not emitted.  (That change already caused more noise in
the regression test output files than I would like.)  Provide some needed
editorial help for comments, clean up code formatting.
