I hate them. I do greps for error messages, and it's annoying as hell if 
it's hard to find.

'checkpatch' is the major reason for them, but I think we've fixed 
checkpath long ago to not warn about long lines if they are due to a long 
string.

Strings should basically be broken up only at '\n' characters, so

	printk("This is a made-up example.\n"
		"Ok like this\n");

is fine, because you can expect to grep for "made-up example", but not 
over the newline.
