The version of man used is man-db, which AFAIK is used by all major
GNU/Linux distributions.

    https://man-db.gitlab.io/man-db/

Looking into this with PIPELINE_DEBUG=1, the processing done is
non-trivial, and depends on e.g. /usr/libexec/man-db/zsoelim from
man-db.  So I think trying to duplicate all of that for the purposes of
this script might not be the best use of our time.

For reference, I've attached the debug output from man.
