Yes, in a squeak-try a while ago. Caould be 3.2?
Something broke IIRC, thinking files are binary.
A comment indicated concreteStream will change to use it.
This did not happen till today, so i guest there are to many problems.
So i want a FileList explicitly using CrLfFileStream without affecting the

Thats the stuff i have to learn. Could you give some hints? A place where this
interaction takes place, where i can put a "self halt"? Related classes,
methods to browse? I like this browsing/examining in squeak, but here i do
not know where to start.
Would be very lucky with an example which creates a Text with a model and
hints where to plug in the debugger to follow this selection-stuff. :)
