what happens to a message having words that also count in good
categories?  remember you don't have only the category and its related
frequencies, you also have counts of how many messages were read and
so on.  if you don't unlearn by re-feeding all the messages with "-d
wrong-category" to delete their statistics first, all the counts from
the first several lines of the database file are wrong!  this will
change ifiles behaviour in future runs.  your script, unless used
_after_ "ifile -d wrong-category" runs, will garble up the statistics
badly!
