>Description:

Unix 98 requires that env(1) take the option -i to destroy the
inherited environment.  This would be identical to the currently
existing - option.  This diff adds a fallthrough so that -i is
handled as Unix 98 specifies.  This does not include a change for
the man page, I did not think it was necessary.

>How-To-Repeat:

env -i gives error about illegal option

>Fix:
