OK, I thought of that, but that seems like a strange thing for the doc to
suggest: customize it to `t', save your bookmark file, then re/un-customize it
back to the default, `nil'.

Is that really the best recommendation?  I have no special problem with it, but
somehow I was expecting something else.  

Whatever the recommended procedure is, I think the doc (for this and
`version-control') should suggest it to users.
