Subject: [PATCH v3 10/17] rv: Fix generated files going over 100 column limit

The dot2c.py script generates all states in a single line. This breaks the
100 column limit when the state machines are non-trivial.
Recent changes allow it to print states over multiple lines if the
resulting line would have been too long.

Adapt existing monitors with line length over the limit.
