* Disable deleting from an empty buffer which can cause a crash.
* Improve on the fix for deleting from the end of the buffer.
* Clean up leftover log.
* Avoid theoretical underflow.
* Implement :before which accepts a time interval and moves the editor to
the closest history state to the commit of the current time minus that
interval. Current time is now by default, or the commit time if :before
has just been used.
* Add :earlier an :later commands that can move through
the edit history and retrieve changes hidded by undoing
and commiting new changes. The commands accept a number
of steps or a time period relative to the currrent change.
* Fix clippy lint error.
* Remove the dependency on parse_duration, add a custom parser instead.
* Fix clippy errors.
* Make helix_core::history a public module.
* Use the helper for getting the current document and view.
* Handled some PR comments.
* Fix the logic in :later n.
