#initialize(real) ⇒ SupremeStderrHack

ridiculous: make a state machine that rewrites part of the error message coming from nanoc, then gets rid of itself when it’s done. This is so fragile and stupid but I really needed to get the nanoc message (“please file bug reports”) out of the error message so ppl don’t misfile bug reports there that are actually NanDoc bugs.
