tdf#125637 - Correctly hand names ending with an underscore
If a name is ending with an underscore at the end of the line, it won't
be recognized correctly and it will be wrongly interpreted as the
respective name without the underscore at the end. Instead of changing
the macro source, use a flag in order to correclty identify the line end.
