Thanks David, for the clue. 

Between you and the log file, and LSR snippet 623, it seems I chose the
worst possible example to try with the parallelogram.

parallelogram =
  #(ly:make-stencil (list 'embedded-ps
    "gsave
      currentpoint translate
      newpath
      -0.3 0 moveto
      -0.3 1.4 1.8 1.3 1.8 0 curveto
      1.7 -1.9 -0.5 -2.5 -0.5 -2.5 curveto . . . etc

Note all the segment names after the coordinates. I missed this before.

But svg backend requires different markup, such as 

customClefStencilTwo = 
  #(ly:make-stencil
    `(path 0.1
          `(moveto 0 0
            curveto 0 1 0.7 2.5 1.5 1.5
            lineto 1.5 -3
            closepath)
          'round
          'round
          #t)
     (cons 0 1.5)
     (cons -3 2))

to help conversion to svg.
I'm back in business!
