Only the command takes these double-dash-style options like "--drop-first". For the function you have a second argument, please see the help for that (haven't used it myself yet). Remark for Allin and Jack: BTW, I think the error message is strange insofar as IMO the parser should complain already about the "--" in there, not about the "drop" word, no? But perhaps this has been changed since last release.
