This will allow us to print precise error message while using `format_set_trailers_options()` in ref-filter. For capturing the invalid argument, we changed the working of `format_set_trailers_options()` a little bit. Original logic does "break" and fell through in mainly 2 cases - 1. unknown/invalid argument 2. end of the arg string But now instead of "break", we capture invalid argument and return non-zero. And non-zero is handled by the caller. (We prepared the caller to handle non-zero in the previous commit). Capturing invalid arguments this way will also affects the working of current logic. As at the end of the arg string it will return non-zero. So in order to make things correct, introduced an additional conditional statement i.e if encounter ")", do 'break'.
