There are other buffer-local minor modes that are of similar nature:
display-line-numbers-mode, display-fill-column-indicator-mode, and
maybe some others (e.g., what about hl-line-mode?).  So if we are
going to preserve text-scale-mode across reverting, I think we should
have a list of modes to preserve, not just exempt this one mode.
