The check-program flag was added to validate the program field in syslog format. It verifies that the program field contains only the allowed characters '[a-zA-Z0-9].-_/()' and requires at least one alphabetical character in the program name. If these conditions are not met, it treats the program field and the remaining fields as part of the log message. This approach avoids using regular expressions to improve performance.
