histedit: improve roll action integration with fold

Previously the fold action would inspect it's class to figure out if it was a
rollup or not. This was hacky. Now that finishfold is inside the fold class,
let's modify it to check a function (which roll can override) to determine if it
should be prompting for a commit message.
