TeX translates every blank line to a \par - these don't matter at the
top-level while definitions are being read (because \par does nothing if
you're not in a paragraph and \par\par\par... is equivalent to \par) - it's
*within* a macro definition that you have to be careful.

How about \raise\xpos\rlap{\kern\ypos#3} instead?
