bug#47277: 28.0.50; enriched-mode: args out of range on 'v' in dired

[Jean Louis]

There is attached file "new". The file was created in enriched mode and
saved.

in latest Emacs, reproducible by:

- C-x C-f to directory with file in my case ~/

- pressing v on file "new"

- error comes: format-deannotate-region: Args out of range: 177, 177
