+% experimental stripping

+%D For a while we had stripping of special chars built into the analyzer
+%D but Khaled suggested to generalize this so I changed the code into a
+%D manipulator there.

+%D \stoptyping

+%D However, in \MKIV\ it makes more sense to also provide it as a more
+%D general feature. Here we implement this as experiment. I might
+%D cook up a few more variants in both variants.
