Francesco, none of the options in that nroff table "user descriptions and options" mentions arguments to any options, with the exception of sslfingerprint that gets it wrong - its intention (as inherited from Eric Raymond) seems to just list the long and their short equivalents, but the redudancy is also a maintenance burden.
What I figured when looking for what you meant is that the --help output also lacks the argument...
--fastuidl do a binary search for UIDLs
So that warrants fixing. And another round of translations... :-o Cheers, Matthias
