"suffix" in "replica" slapd.conf directive deprecated?

[Andreas <andreas@conectiva.com.br>]

openldap-2.1.30

slapd.conf(5) states, for the "replica" directive:

"Zero  or  more suffix instances can be used to select the subtrees that will
be replicated (defaults to all the database)."

I was (still am, actually) having problem with a replication setup and went to
take a look at the code:

servers/slurpd/config.c:512
(...)
       } else if ( !strncasecmp( cargv[ i ],
                        SUFFIXSTR, sizeof( SUFFIXSTR ) - 1 ) ) {
            /* ignore it */ ;
        } else if ( !strncasecmp( cargv[i], STARTTLSSTR, sizeof(STARTTLSSTR)-1 )) {
(...)

Am I reading this correctly? Is the "suffix" option being ignored?
If yes, why?
