[NTG-context] Can I use language as a mode (set on the command line) and simplify this?

Hi Gerben,

I think this may do the trick:

  \doiftext{\env{ml}}
    {\mainlanguage[\env{ml}]}
  \starttext
   Document main language:
    \startmodeset
        [**en] {English}
        [**es] {Spanish}
        [**de] {German}
        [**nl] {Dutch}
        [**ru] {Russian}
    \stopmodeset%
   .
  \stoptext

Of course, "--arguments=ml=nl" would be the right option to pass the
language from the command line.

AfaIk, there is not "--language" option from the command line. (This
also makes sense to me.)

Just in case it might help,
