And 'env' would not help much, because its output can easily be confused
by environment variable values that contain newlines:
$ foo='not
POSIXLY_CORRECT=1'
$ export foo
$ env | grep POSIXLY_CORRECT
POSIXLY_CORRECT=1
P.S. This is precisely why GNU coreutils recently added the -0/--null
option to env.
