Right, so then you don't get the caret by default.  You can still enable it
with a flag if you want.

Actually, it's not clear to me that the caret line would be likely to cause
trouble for IDEs in any case; they already have to deal with output that isn't
a specific error.  Maybe we should just turn it on by default in all cases, and
possibly backtrack to only on a tty if it causes problems.
