I'll add support for:

\starttext

\hsize6cm

    \pi\ = 
\hyphenateddigits[\unknown]{3.141592653589793238462643383279502884197169399375105} 
  \blank
    \pi\ = 
\hyphenateddigits{3.141592653589793238462643383279502884197169399375105} 
            \blank
x $\pi  = 
\hyphenateddigits[\unknown]{3.141592653589793238462643383279502884197169399375105}$ 
\blank
x $\pi  = 
\hyphenateddigits{3.141592653589793238462643383279502884197169399375105}$ 
          \blank

\stoptext

A quick and dirty hack as we don't need some full blown mechanism for 
such a rare case.
