@davisp: I did fix `_replicator` part of a PR.
> Isn't that obviously broken then? How would you ever match something with
'/' in it to filename:basename(Anything)?
basename is needed to extract last component of the path. The
`couch_db:normalize_dbname` makes sure we strip `couch` extension,
creation_time and whatnot.
