#4239: [with patch, needs review] fix for problems with zero kernel and images
----------------------+-----------------------------------------------------
Reporter: fwclarke | Owner: tbd
Type: defect | Status: new
Priority: major | Milestone: sage-3.1.3
Component: algebra | Keywords: kernel, image
----------------------+-----------------------------------------------------
Computation of kernels and images of linear transformations over `GF(p)`
(`p` odd) and `CC` fails when the result is zero.
The patch solves the problem by adjusting
`FreeModule_submodule_with_basis_pid` so that a `tuple` of generators gets
changed into a `list` (something that happens anyway if `check == True`).
New doctests have been included.
