Small unrelated cleanups.

- In missing_references.py, splitting on ":" will work even if ":" is
  not in the string.
- Just a linewrap in backend_pdf.
- In backend_ps, we can just printout the whole psDefs in a single shot.
  (the few extra spaces not stripped out don't affect the validity of
  the PS file and if we *really* worry about the tiny impact on the file
  size we should just pre-strip the contents of psDefs).
- rcsetup.validate_sketch is really just validating that its input is
  None or three floats.
