psql: initialize comment-begin setting to a useful value by default.
Readline's meta-# command is supposed to insert a comment marker
at the start of the current line. However, the default marker is
"#" which is entirely unhelpful for SQL. Set it to "-- " instead.
(This setting can still be overridden in one's ~/.inputrc file,
so this change won't affect people who have already taken steps
to make the command useful.)
