Tom Lane b0d8f2d983 Add SHELL_ERROR and SHELL_EXIT_CODE magic variables to psql. ...

These are set after a \! command or a backtick substitution.
SHELL_ERROR is just "true" for error (nonzero exit status) or "false"
for success, while SHELL_EXIT_CODE records the actual exit status
following standard shell/system(3) conventions.
