Hi,
it turns out to be reproducible this way:

a lot more errors happen with COLUMNS=20.
Tested on x86_64-pc-linux-gnu.
Is it OK for trunk?
Thanks

So while you've got a patch here, you haven't indicated what the problem
actually was. I'm guessing caret_max_width was uninitialized and thus
we got random-ish values. Presumably those randomish-values are what
caused tests to occasionally appear to truncate their output and fail?
If that's the case, this is fine. If it's something deeper, please
provide a bit of background to help in evaluating the patch.
Thanks,
jeff
