This is a pretty gross commit, since it also includes a lot of
unrelated refactoring, especially of how error messages are printed.
Also adds a lint recipe that prints lines over 100 characters
To test, I added a `--color=[auto|always|never]` option that defaults to
auto in normal use, but can be forced to `always` for testing. In `auto`
mode it defers to `atty` to figure out if the current stream is a
terminal and uses color if so.
Color printing is controlled by the `alternate` formatting flag.
When printing an error message, using `{:#}` will print it with colors
and `{}` will print it normally.
