Why does bogofilter need bash?

My bogofilter distribution doesn't seem to include the third file,
but the other two use shell functions.  Classic sh can not handle
those.  Current sh versions do handle them.

I also spotted an argument construct in randomtrain - ${1:0-1:1} - that
I'm not sure classic sh would handle.

I didn't try running the scripts with sh.
