No problem, and thanks for sending an updated patch.

I think this should be a boolean called `recentf-verbose` or even
`recentf-messages`.  If there is a strong need for more fine-grained
control, we can always introduce an integer option later.

I would also set it to nil by default, because as we discussed earlier
these messages are unlikely to be useful.  We should of course then also
explain in NEWS how to get the old behavior back.

I think the comments here are superfluous; the `write-region` interface
should be well-known to anyone looking at this code.  That last part
could probably just be (with the boolean option):

    (and recentf-verbose 1)
