No, it was caused by having a space after text and before the newline.
Use of $(NULL) helps multi-line comments be extendable in the future -
you only have to insert one line at the end, instead of modifying an
existing line to add a \ as well as your addition. But when everything
fits on one line, there is no point to using $(NULL).
yes, I retry it, as you said.
