Hello

Is there a way in ConTeXt to allow line-breaking by default after an en or em dash (-- or ---)?  The equivalent of \XeTeXdashbreakstate=1

I couldn't see anything after trying various searches.

Conversely, is there a way of inhibiting ConTeXt from hyphenating an already hyphenated expression (great-grandfather etc.)?  That is usually seen as a desperate last resort (which the user can invoke manually with \-).
