Error messages and newlines

It looks like xrepl isn't printing a newline before [, bt for context] in some cases:

In this transcript the first interaction is missing a newline, but it isn't missing in the second one.

Well, judging from this line of code, the difference here may be intentional. If so, that's okay with me, but I did find it confusing to not see the familiar ",bt..." message (and then noticed it was in a different place).
