Use 'snazzy' colors/spacing on precommit script as well as lint script

[rootwork]

Great project!

If I run the lint script, I get errors helpfully formatted by snazzy.

But when the precommit script runs, the colors and some of the spacing from snazzy don't show up (though the overall formatting of the errors does).

It'd be nice to have the output of each be the same for the linting section.
