Here in the commit log you need entries for the files you change and the
functions you change in them.  See
036cc149e6e52722f16ef25f4203e82abae9bc79 for an example.  I know it's a
bit of a drag but it's how it is.  (In Magit, if you use that, you can
press C in a diff to make a template in the log.)

Please limit lines to < 80 characters.  If you use emacs, you can fix
with M-q, provided your fill-column is set appropriately.

Is --print-errors the right thing here?  I guess this causes some text
to spew on the console for 2.0.  Probably not the right thing if we're
going to fall back.

Otherwise good.  Apologies for the nit-picking; I'm doing it now just so
that things are fluid in the future :)
