block output doesn't work with frozen string literal

[andrcuns]

Looks like the internal logic tries to change existing string when # frozen_string_literal: true is present and output_style is set to block. Did not try to dig deeper, but here is the stacktrace:

Traceback (most recent call last):

Where are you enabling this flag? It sounds like you are using it from the cli via --enable=frozen_strong_literal or some other global flag, correct?

Pretty much in every ruby file both in my personal as well as work related projects I use the frozen string literal comment on top of the ruby files which is enforced by rubocop rule.
I would imagine many projects do that as it might become the default behavior in future ruby versions.

Fixed in 0.7.1
