3.11pre7: LOGABSTRACT bug

it seems that LOGABSTRACT=all doesn't quite work with 3.11pre7.
More specifically, it doesn't log anything for pipe recipes, even though the
manpage specifically says that an entry is logged for every successfull
delivering-recipe.

example:

        ~-0% cat ~/tmp/tmprc                      
        LOGABSTRACT=all
        
        :0 c
        | cat >/dev/null
        
        :0 c
        /dev/null
        
        :0
        /dev/null
        ~-0% procmail ~/tmp/tmprc <~/mail/inbox/1
