I for one would definitely like backslash commands with very wide
output to be wrapped by default.

Doesn't this suggest that we need an "auto" formatting mode which has
the semantics "let psql decide what format mode I want"?

Then the people who object to wrapped mode can just set formatting to
aligned explicitly and be done with it.

I seem to recall there was some discussion of an "auto" mode in the
original wrapping thread, but if there was any meaningful conclusion I
lost it in amongst the width detection flame war.
