debug.traceback() oddity

I'm trying to use the level parameter described in the docs for
debug.traceback(). However, I'm finding that it doesn't appear to work
as described --- instead, all the parameters get concatenated and become
the error message. For example:

> =debug.traceback()
stack traceback:
	stdin:1: in main chunk
	[C]: ?

...works as expected. But this:

> =debug.traceback(nil, "foo", 1)
1

...isn't. Experimentation reveals that:

> =debug.traceback("foo", "bar", "baz", "boo")
foobarbazboo
stack traceback:
	stdin:1: in main chunk
	[C]: ?

...which is very odd.

What am I missing here?
