["unset functions '# !'" insufficiently documented]
IMO, there are good reasons for not doing so and for not given any
OS/shell versions, because nobody really knows and nobody really needs
to know, nor is it of much importance nowadays ... You'll very soon
notice should you once hit an OS or a shell which doesn't ;)
However, Sven Mascheck has a pretty comprehensive overview on these
topics on http://www.in-ulm.de/~mascheck/bourne. Unfortunately this page
currently doesn't seem to be accessible (Google seems to have it in its
cache. Google for "sven mascheck shell ulm")
