Yes, but my patch grabs COLUMNS before we call readline(), so we use the
COLUMN value we were invoked with, rather than tracking the changes
readline() makes to it.
If we use COLUMNS as set by readline, there is no way to pass a COLUMNS
value into psql reliably.
'ls' doesn't use readline so it is safe from changes while it is doing
its output.
I can pull COLUMNS as modified by readline() but I thought no one wanted
that.
