I talked to Greg on IM and he had a new idea, related to my 'auto' idea
of using aligned/wrapped/expanded mode automatically.

His idea is that 'auto' mode (aligned/wrapped/expanded) is only for
output to the screen, and 'wrapped' is always wrapped. 'Wrapped' would
be affected by \pset columns, COLUMNS, or the terminal width for output
to screen, file, or pipe. If no width could be derrmined for wrapped,
it would default to 72.

This gives us 'wrapped' that always wraps (if it can fit the headings),
and most people will use 'auto' in their psqlrc, and it affects only
terminal output.
