I'm not sure, given that the main reason for splitting strings in the first
place is to avoid LONG_LINE_STRING warnings, I think we must choose between
the two options. If split strings are not allowed, then long lines must be.

Since checkpatches.sh is used by various automated scripts to complain
loudly about problems in submissions, the above change prevents maintainers
from writing long string at all (can't split and can't go past 80 columns).

As a result, they will be tempted to cripple their code with nasty
workarounds to shut up checkpatches.sh, we don't want that to happen.

Also I think the reasons stated by original commit cf75514c8e2e are still
relevant. My vote would be to keep things as is.
