My feeling that this job would be much better done by a preprocessor to
[nt]roff. While one can write amazing (and convoluted) macros to
do almost anything, it is not really suitable for algorithms with
interation, arrays etc. Anyway as evidenced above it is rather slow!

It is probably quite easy to write a quick and dirty awk filter
as a preprocessor which may optionally call sort to do the dirty
work. Any volunteers?
