Replying to [comment:7 hivert]:
I agree that there are many more cases where this type of list formatting
could be useful, and indeed the code is general enough to work with any
type of object whose repr spans multiple lines. The issue is simply
choosing which lists to format specially (in print_obj()).
In one of my earlier iterations of the displayhook, I applied the special
list formatting to every "tall" list. But when I ran testall I found that
some objects just didn't work well with the formatting. So I think that
applying the hook always is a mistake, and besides would introduce many
more doctest headaches. Having objects "opt-in" by including a special
field or method that tells the displayhook to use the special list
formatting sounds like a good idea though.
This kind of work should definitely be done, but in another ticket. We
will have to come to an agreement about these design issues. For now,
let's get this patch into Sage.
