OK, will do.

I just realized it might be more important to add support for GPU
specific options.

(E.g., I saw -pla=1 mentioned in some john-dev threads.)

Can someone post john's usage output for a CUDA/OpenCL build, or
alternatively, point me to a mini-howto to setup such a build on my
laptop, so that I can see what needs to be added?

I hope my laptop is suitable to build john with GPU support.

$ uname -srv

01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro

I probably need to install a proprietary driver, and the GF108 isn't the
fastest nVidia card, but this shouldn't prevent me from using the GPU
for john, even if only to find out which additional options need to be
supported by the bash completion script.
(Do we even need additional --list= values, to list the available GPUs...)
