The note in says there are two ways to deal with
environment variables, "reset" w/whitelist or
no-reset w/blacklist.  Then it tells you:
"In all cases, environment variables with a value beginning with () are
     removed as they could be interpreted as bash functions. "

sudo is seriously broken in this regard, though I can't
see where / when this change went in (i.e. quite possibly,
been there, and my auto-scripted files reread in the definitions).
