[NTG-context] Typesetting abbreviations

What is the correct way to typeset an abbreviation in ConTeXt? The space after the full stop seems too big and if I use \thinspace, I cannot use ties. No command - space is too big \starttext Mr. John Doe \stoptext With tie - space is too big \starttext Mr.~John Doe \stoptext With \thinspace - looks right except at an end of line \starttext Mr.\thinspace John Doe \stoptext Any suggestions are welcome! Thanks, Clyde
