Hi Paul,

[Yes I was thinking you code warriors could do without an example...]

How's this:

MULTILINE_TARGET        = foo   \
                        bar     \*** any non-tab whitespace here causes problem

Ahh! I don't think this is adequately documented.
Would it be possible to change to the more intuitive standard syntax:
  [Makefile,12]: *** ...
