Visible already in sage7.1v, difficult to get a good minimal test case.

 Summary changed from Fix collect_common_factors() to accept any expression to Doctest: Fix collect_common_factors() to accept any expression
Actually the fix was unintentional and is in Pynac0.7.10. This will add doctests.

If you rebase the branch, I will review this.
