Bogofilter already has '-t' for "terse" mode.  The default output format of 
"%1.1c %f" produces values like:

N 0.000000
Y 0.999999
U 0.500000

Using bogofilter.cf the format is redefinable as are the spamicity_tags, 
i.e. 'Y', 'N', 'U'.  There's no need for adding '-O'.

As to changing the error exit from 2, my bet is that people use '-e' and 
check for 0 or non-zero, with the rest checking for 0, 1, or "other".  None 
of these people will be affected by the change from 2 to 3.  The addition 
of a value for Unsure, is probably not harmful.

... still waiting to hear from someone that will be adversely affected by 
the change ...
