Yeah, but those are all deleted as well.  Suppose I have these first three
lines in my .idata file:

    python ifile cron cars
    9000 1204 6975 6240
    28 6 24 18

and I delete "cron" as a category.  Then the first three lines will be:

    python ifile cars
    9000 1204 6240
    28 6 18

All frequency pairs that begin with "2:" will be deleted.  All frequency
pairs that begin with "3:" will now begin with "2:".  Any words that no
longer have any associated frequency pairs - because they were only ever
associated with the category "cron" - will be deleted altogether.

If I read the format description in the FAQ correctly, I think that's what's
supposed to happen.  What else am I missing?
