does this preserve todo keyword font locking and sorting? it is an interesting change if so, and i would probably find it useful.
does archive work the same way? i presume it is a coincidence that this message comes after mine which mentioned font locking and sorting, as the fix to that message is to not evaluate or export call lines that are not supposed to be exported. i would not find this change to be a suitable workaround for that. however, i like the idea of commenting out a headline not changing sorting and font locking. i have always called these quasi-keywords.
