ANSI C/C++ allows:

"foor"
"bar"

and the compiler will glue the parts back together as "foobar". 

However, i often don't like the resulting code layout. I also think
there might be a bug in checkpatch. The relevant code is:

#80 column limit
                if ($line =~ /^\+/ && $prevrawline !~ /\/\*\*/ &&
                    $rawline !~ /^.\s*\*\s*\@$Ident\s/ &&
                    $line !~ /^\+\s*printk\s*\(\s*(?:KERN_\S+\s*)?"[X\t]*"\s*(?:,|\)\s*;)\s*$/ &&
                    $length > 80)
                {
                        WARN("line over 80 characters\n" . $herecurr);
                }

my perl is not good, but it appears to be looking for KERN_, eg
KERN_ERR, KERN_WARNING etc, and maybe should be ignoring such lines?
