The patch is implementing what is declared to do. Shell return code is now accessible is psql var.
Overall code is in a good condition. Applies with no errors on master.
Unfortunately, regression tests are failing on the macOS due to the different shell output.

Since we do not want to test shell output in these cases, but only return code,
what about using this kind of commands?
postgres=# \! true > /dev/null 2>&1
postgres=# \echo :SHELL_EXIT_CODE
0
postgres=# \! false > /dev/null 2>&1
postgres=# \echo :SHELL_EXIT_CODE
1
postgres=# \! nosuchcommand > /dev/null 2>&1
postgres=# \echo :SHELL_EXIT_CODE

It is better to use spaces around "=".
+ if (WIFEXITED(exit_code))
+ exit_code=WEXITSTATUS(exit_code);
+ else if(WIFSIGNALED(exit_code))
+ exit_code=WTERMSIG(exit_code);
+ else if(WIFSTOPPED(exit_code))
+ exit_code=WSTOPSIG(exit_code);
