	Make sure the 'exit' command as well as 'exit $val' command exits
from environment scripts immediately and propagates return value
out of those scripts fully. That means the following behavior is
expected:
"
=> setenv foo 'echo bar ; exit 1' ; run foo ; echo $?
bar
1
=> setenv foo 'echo bar ; exit 0' ; run foo ; echo $?
bar
0
=> setenv foo 'echo bar ; exit -2' ; run foo ; echo $?
bar
0
"
As well as the followin behavior:
"
=> setenv foo 'echo bar ; exit 3 ; echo fail'; run foo; echo $?
bar
3
=> setenv foo 'echo bar ; exit 1 ; echo fail'; run foo; echo $?
bar
1
=> setenv foo 'echo bar ; exit 0 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit -1 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit -2 ; echo fail'; run foo; echo $?
bar
0
=> setenv foo 'echo bar ; exit ; echo fail'; run foo; echo $?
bar
0
"
