Even though I can't find it, it must be there as I see in the sources
(line-interface.cc)
"Generic line objects. Any object using lines supports this."
" The property @code{style} can be @code{line},"
" @code{dashed-line}, @code{trill}, @code{dotted-line},"
" @code{zigzag} or @code{none} (a transparent line).\n"
which tells me that zigzag is the closest thing currently available.
And as for drawing a wiggly-line this would mean adapting
Line_interface::make_zigzag_line () earlier in the same file.
But that requires some knowledge of the drawing primitives available...
