文档:

Determines the appropriate autoload value for an option based on input.

This function checks the provided autoload value and returns a standardized value ('on', 'off', 'auto-on', 'auto-off', or 'auto') based on specific conditions. If no explicit autoload value is provided, the function will check for certain heuristics around the given option. It will return auto-on to indicate autoloading, auto-off to indicate not autoloading, or auto if no clear decision could be made.
