When only one directory is wanted (allowed), the task is simple, i.e. given 
an ordering, take the strongest.  Whether environment or configuration 
should be stronger depends on the environment.  Some admins might want the 
cfg/env/cmd order you give.  Others might want cfg (as specified by the 
admin in /etc/bogofilter.cf) to override env settings.

For multiple wordlists, when all of config, HOME, BOGO, and command line 
are specified do we use all the wordlists found?

When updating wordlists, which directory gets the changes?

Like a kid with a hammer who wants to use it for all jobs requiring tools, 
I'm inclined to suggest config file options to control directory ordering 
and naming of update directory.  I also know I'm sometimes inclined to 
create too many options.  How do all you other bogofilter users want this 
handled?

I took a look at the code last night.  Some work is needed as multiple 
directories are not being properly added to the list of wordlists.
