I agree. My argument wasn't that 80 columns is bad or useless, but that
some people might prefer other values. A formatter without any
configuration options is bound to make some people unhappy. So I argue that
the tools should be configurable.
As Bengt and Tuncer pointed at, one may use a standard format when
committing the code, so that the repository has an uniform format, but when
checking out would like to see the code differently. It would be a waste to
use two different tools for that, instead of one with different
configuration. The default format should be something that most people can
agree upon, because my guess is that after a while only a few will keep
converting the code back and forth when editing it.
