You're right, user-visible strings shouldn't be splitted. The 80-char limit has
an exception about this (qouting Documentation/CodingStyle):

""
  Chapter 2: Breaking long lines and strings

[..]
Statements longer than 80 columns will be broken into sensible chunks, unless
exceeding 80 columns significantly increases readability and does not hide
information. [..] However, never break user-visible strings such as printk
messages, because that breaks the ability to grep for them.
