Fixed new bug the previous fix introduced:

false
foo=bar
echo $?
would print 1
Also fixed the long standing bug:
false
echo `echo $?`
would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient

IEEE 1003.2 (D11.2.2.3) requires that the system's true and false be accessed

instead of searching $PATH. The best way to satisfy this requirement is to
