ValueError on formatting a valid tox.ini

[Julian]

Hi! (I don't know if this isn't yet intended to be used or not, if so apologies) --

Just tried to run it and got a ValueError with no message.

git clone https://github.com/Julian/regret && cd regret && tox-ini-fmt tox.ini should reproduce (I didn't look carefully at what's happening, so apologies if it's something simple):

⊙  git clone https://github.com/Julian/regret && cd regret && tox-ini-fmt tox.ini                                                                                                                 julian@Air

Ah, as I'm pasting the traceback here, perhaps the explanation is just saying the parsing logic is confused by newlines.
