Latest version of RuboCop now only performs auto-corrections from "safe"
cops when given the `--auto-correct`/`-a` option. To run
auto-corrections from all cops, including "unsafe" ones, you must now
pass in `--auto-correct-all`/`-A` instead.
The new `rubocopfmt-include-unsafe-cops` defcustom defaults to no `nil`,
for backwards compatibility. Turn on unsafe cops by setting it to `t`.
Large portions of rubocopfmt.el is based on code from go-mode.el. As
such rubocopfmt.el should really carry the same license and copyright
as go-mode.el does.
