avoid splitting namespace blocks unnecessarily * fcn-info.cc, ft-text-renderer.cc, gl-render.cc, gl2ps-print.cc, oct-stream.cc, symtab.cc, pt-cbinop.cc, pt-eval.cc, pt-idx.cc: Don't split namespace blocks unnecessarily. Omitting static functions from namespace blocks was done because of a misunderstanding.
