You german guys love shortcuts so much  ... 

\starttext

\definetextmodediscretionary :
  {\prewordbreak\kern.25em:\space\ignorespaces}

\definetextmodediscretionary ;
  {\prewordbreak\kern.25em:\space\ignorespaces}

\definetextmodediscretionary *
  {\prewordbreak\discretionary{-}{}{\kern.05em}\postwordbreak}

\startlanguagespecifics[de]
  \installcompoundcharacter "| {|*|}
\stoplanguagespecifics

\de \hyphenatedword{hinauff|*|liegen} \hyphenatedword{hinauff"|liegen}

\stoptext

i think that the : and ; are handy for french and we can still abuse the *
for the ligature killer (btw, this one is like |~|). I think that .05 is
better than .03 

this only works with the version i uploaded saturday [the definable
discretionaries were needed for GB's speech module]

PS. Tobias, it this okay? If so, i'll move it into the lang modules.
