 IIRC that was done with the understanding that some control RFCs
 would have to be rewritten - but apparently nobody volunteered
 to do the rewrites.

 Though the new behavior may be formally compatible with both RFCs,
 it certainly breaks the expectations of one of them and must do so.

 How long has the previous behavior been in in OpenLDAP?  Is it
 feasible to delay the change until RE25?  Seems like a typical
 kind of change to avoid doing in the middle of a release series.
