PRINT_EXIT_VALUE option in scripts

PRINT_EXIT_VALUE option in scripts

[Vincent Lefevre]

The PRINT_EXIT_VALUE option doesn't work in scripts or when a file
is sourced:

----------------------------------------
#!/usr/bin/env zsh

echo $ZSH_VERSION
setopt PRINT_EXIT_VALUE
/bin/false
echo OK
----------------------------------------

ypig% ./tst
5.0.2
OK
ypig% source ./tst
5.0.2
OK

This was already the case with zsh 4.3.10.

Is this intentional? The man page just says:

   PRINT_EXIT_VALUE (-1)
      Print the exit value of programs with non-zero exit status.

Either the behavior or the documentation should be fixed.

Looking at the code it's not entirely clear to me what the determing
factor is, but the following weasel words ought to do it.
