I can't take credit for writing that particular entry in the manpage,
but it's excellent that you caught this.

I don't understand i_deblocking_filter_alphac0, i_deblocking_filter_beta,
or i_cabac_init_idc, so all of those could use better explanations as
well. I realize the two parameters affect the loop filter, but I have
no idea what's meant by alpha and beta.
