I had thought of that, but it would look messy with thousands of 
prefixes.  The way to do it would be to pad every prefix up to the 
length of the longest one, like so:

_44871
_44870
_4480X
_4477X
_4478X
_4479X
_441XX
_442XX
_44XXX

However, this means the program generating the extensions.conf file 
needs to think about how much padding is required, and I am keen to find 
a mechanism that is just a little more elegant.
