@xvw Please add the no-changelog label.

Since we do add usef-facing changes (a new configuration option) we should add it to the changelog :-)

Thanks for the changes, Pizie, overall this looks good to me, I just think we should map the targets to get names that actually start with a distinct letters (namely, rename match-next-case and match-prev-case.
