yes, the only question is how do you establish/specify _which_ positions!
We seem to have now established a consensus that we want to do something
different with the global cfrom/cto than was originally intended, so somebody
has to document that. I was actually assuming that anyone who wanted the
global cfrom/cto would implement it by calculating max/min on the token derived
values, and as soon as you said you were passing the cfrom/cto values it became
clear that this was not the case.
Since we started on this - there are issues with the tokeniser - e.g., you have
a string `abc d ef' - the preprocessor tokenises to `ab' `x' - what is the
cfrom/cto for those tokens? Have you got a specification for what you're
doing, and if so, could you show Ben, please?
