I've pushed a fix to master for this (commit 3812e17978).

Essentially it takes Drew's suggestion.  I left "C-x r m" as `bookmark-set', with the same behavior it has now, and "C-x r M" sets a bookmark but errors if it would overwrite an existing bookmark of the same name.

I didn't go with Stefan's suggestion of using RET RET instead of RET, because you can't habituate to it.  You don't necessarily know in advance whether you're setting a new bookmark or updating an existing bookmark, so you can't predict whether you will need to hit RET or RET RET.  Better to offer two different commands, and those people who want one style all the time can just use the appropriate command all the time.

Comments and further discussion welcome, of course.  Thanks, Leo, for raising this issue, and thanks Drew and Stefan for helping think things through in the bug ticket.

Occationally I have overwritten bookmarks with regrets. So maybe
something along the following lines is needed.
