Add optional start/end parameters to tp-forward-do and tp-backward-do
The function parameter now supports optional second and third arguments: - (function text) - backward compatible with existing code - (function text start) - receives match start position - (function text start end) - receives both start and end positions This uses func-arity to detect how many arguments the function accepts and passes the appropriate parameters.
