allow process exit status to be determined by macros
* Any value left on the numeric stack now determines the exit code.
This ensures you can call n^C as the SciTECO version of exit(n).
It will also work with n$$ in the top level macro.
But you don't necessarily need any of these commands.
* Could be useful in shell scripting as in
`sciteco -e "@EB/file/ :@S/foo/\"F1'"` to fail `foo` is not found.
