Styles: Revisions Description Text

[pablohoneyhoney]

For clarity and guidance, I'd consider going from:

Revisions are added to the timeline when style changes are saved.

to:

Restore styles from an earlier version of changes that was automatically added to this timeline when new styles were saved.

or

Restore styles from an earlier version of saved changes.
