Except for extreme cases, unlike for e.g. sysctl, I think it is dangerous
to compile this out altogether.
Further, nit: While I let Penny's use of "Wrap around ..." as subjects go
as is, the massive use here makes it necessary to indicate that I don't
consider these as meaningful subjects. They simply don't say what is
actually being done by the patch. One possible meaning could be that you
found line wrapping issues, and correct them step by step.
