[9fans] arginit and argopt in arg(2)

[Lyndon Nerenberg]

arg(2) refers to arginit and argopt in NAME, but neither exists anyplace I 
can get to (including all version of libc.h in sourcesdump). Are these a 
holdover from pre-4ed? I lost my 2ed CDs so I can't look back before 
what's in sourcesdump.
