yeah, like my first quick solution; but hacking the C src gots a faster 
and better solution.

that hack was somewhat talored to the spam,ham case, ie 2 cat.s; but ifile
sorts ratings and the patch always considers top 2 ratings, hence if you 
need to decide where to put a msg among several (+2) cat.s, usually you need
to know just the winning one, and maybe the next closest one. For more cat.s
I don't think you'd need to consider all combinations (well, depends on what 
you want to do), but I'd extend the patch to have ifile say eg:

categories: spam,ham,cheese,fruits...

ifile -T 20,3 -q -c msg


ie '-T x,n': consider threshold x among up to top n cat.s.
kinda 'fuzzyfier'...
