I haven't heard any new ideas of how to resolve this issue in the past
few hours so I will throw out two new ideas.

Have a 'format=auto' mode that does aligned/wrapped/expanded, but only
for screen output --- file/pipe would still use aligned. And have
'format=wrapped' affect file/pipe by requiring the user to specify the
width, or use a default of 72.

Another idea is to require the user to specify the file/pipe output
width when they define format=wrapped, e.g. format=wrapped:75. If they
don't specify the width, 'wrapped' doesn't affect file/pipe. (Perhaps
the width controls screen width too.) (That is effectively what \pset
columns does, but this is more integrated.)

I have heard why people want 'wrapped' to affect file/pipe output, but I
have not heard a clear explanation of why people don't want that. I
personally think that having the screen width affect the width of
file/pipe is odd, but if the user specifies the width, it seems fine to
me. What is the objection?
