If we keep people's internal parsers working properly, I think having
a line of three characters too long is a fair compromise. Besides
that, there are a lot more lines of code in that file that need to be
brought back to under 80 characters.

If you really care about that line length, precede with a patch (or
two) that changes those insanely long (local!) variable names, so that
you can break up the line right away.

Have fun,
