-> Invalid modifier in string
My bad. Using XEmacs myself. Forgot to escape the \-character in the
docstring. Changing to:
"Escape the characters *+-\\^$ in STR. Return the new string."
should hopefully work fine.

Perhaps so. But I use it in pretty much everything, so I'd have to
invoke it in tons of hooks (or alternatively just in find-file-hooks).
But then you also clutter the modeline with yet another minor mode
thing. Well, I guess it all boils down to your preferences. If there
exist some convention, though, I'm not objecting very much to
following it.

It updates, e.g., copyright strings or modification times. If you
always have the minor mode enabled while editing then I guess this
wouldn't be much of an issue.
