FWIW. Updated my povr branch to always warn on degenerate triangles and 
degenerate triangles, or not, any invalid identifiers/tokens are always 
flagged as errors by name. Your code as posted now generates:

Parse Error:
Invalid identifier 'obj'
prior to valid triangle or smooth triangle.

Parse Warning:
4 degenerate triangle(s) dropped from mesh with
0 valid triangle(s).
File 'newDegenWarn_wIdentErr.pov' line 18:
Parse Error:
Invalid identifier 'obj'
prior to valid triangle or smooth triangle.
