As I recall, the precedent for this procmail recipe is SpamAssassin.

In normal SA usage, 0 indicates spam and the goal is to divert the 
message.  In the other mode, 0 indicates SA ran successfully (and non-zero 
indicates error).

With no flags, bogofilter operates in the first mode.  Using the "-e" flag 
gives bogofilter the second mode.

Let's keep the procmail example as it is.
