Fair enough.

And I have to admit that doing your grep with an additional -4 to see
some context does make a fairly strong argument for your patch.

The code in drivers/isdn/hisax/hfc_usb.c that triggers is absolutely
disgusting, and does crazy things due to the long lines.

As is some other code that grep shows.

In fact, I think that grep convinced me that you are right about this
particular pattern. Brr. Now I need to go dig my eyes out with a
spoon.
