Indeed, you're right. Thanks for pointing that out.

I was mislead by the ambiguous documentation in the PHP manual[1], which
states:

| Contains the current script's path.

The CGI 1.1 specification[2] clarifies this:

| The SCRIPT_NAME variable MUST be set to a URI path (not URL-encoded)
| which could identify the CGI script
