If you're going to cite Knuth as a reason for the 80 character per line
limit, you should understand the difference between ribbon length and
line length.

While there are good reasons to constrain the number of characters in a
ribbon, and to prohibit too much of a shift in indentation between two
neighbouring lines, there's no particularly strong readability reason to
limit a line to 80 characters.

Thus, assuming that maintainers read the patches they're sent, and apply
a bit of common sense (insisting on sensibly sized ribbons, and getting
grouchy about deep indentation), an 80 character line length limit isn't
needed.
