 The count column of the output of `v.category option=report` refers to the
 number of vector objects (i.e. feature count) rather than to the number of
 unique categories (i.e. category count). The latter, however might be
 erroneously assumed because of the modules' name (i.e. that it reports
 category related information). Anyway, I think that both information is
 valuable to a user. However, what is actually provided by the count
 column, i.e. that it is a feature count  is not explicitly clear from the
 manual page and should be improved. Maybe also an option to obtain the
 number of unique categories might be interesting for many users. (Based on
 an GRASS list email conversatoin with M. Lennert, this can be done with
 something like `v.category YourMap op=print | sort -n | uniq | wc -l`)
