The commit 4bcc595ccd80decb4245096e ("printk: reinstate KERN_CONT for
printing continuation lines") allows to define more message headers
for a single message. The motivation is that continuous lines might
get mixed. Therefore it make sense to define the right log level
for every piece of a cont line.
This patch allows to copy only the real message level. We should
ignore KERN_CONT because <filename:line> is added for each message.
By other words, we want to know where each piece of the line comes
from.
