HTML tag cleanup

Effective with earlier commit e2c5229e854e2ef62585f919a15660cba2489b04,
messages are wrapped with <html> tags at display time, rather than
when messages are saved.

For consistency, this commit removes tags from a status message, because
they, too, will be added back at display time.
