Mishandling of multiline strings in user libraries

[Jost]

Have the same problem, therefore I asked:

How to include library code without comment on each line?

#include is a great tool to structure and re-use your code. But: How can I stop the counting comments in the included code? (Every code line is suffixed by something like "// library marker namespace.name, line #".) if it is not yet possible, could we get an option to turn this on/off? Or, maybe another directive, e.g. #includeflat?

Till now no answer...
