The posix spec says a command line prefixed with '+' should be
executed even when -n -q or -t are given.

The patch below implements this for -n at least.  
I took a sleazy out for -jN, ie. use CompatRunCommand when jobs
discovers a + prefixed command and we are not otherwise going to
execute it.  The unit test shows this works ok.

BTW, I'd incorporate the compat test I posted earlier into
unit-tests/posix - assuming both changes go in.
