Yay, I just noticed that the fine people from Notepad++ did upgrade to the latest Scintilla code a week ago.
As such there is now a DataFlex lexer in their codebase.

This means that it will be much easier to get them to accept my changes for supporting DataFlex out of the box (they still need some changes for that, but I made those in my fork). I might have some time to look into this soon.
