this is unrelated to his code.  not throwing an error with unknown option is 
not the same thing as accepting it.  we should add logic that rejects all 
unknown options.  that would result in -n being rejected by common code when 
support is turned off.

so, ignoring his patch completely, current code does not throw errors when 
doing things like:
export -n
export -Z
export -askdlfjasklfjasklf
-mike
