Long ago, Jiri Slaby noted that the subsequent printks should be
pr_cont. Let's instead get rid of the multiple printk calls.

I originally suggested getting rid of the extra printks by building a
suitable string at compile time, but then ended up going out on a
tangent. Since I've basically shelved the COND_CONFIG idea and
288cf3c64e anyway makes it impossible to build the entire string at
compile time, I now suggest this.
