Thank you for this patch and my apologies for the delay in reviewing the
change!  It took me a little too long to understand the problem and then
even longer to decide whether we should include this workaround or if
there was an alternative that could improve the handling of unspecified
inputs all together.

I ended up splitting it up into two commits: one that names the values,
the other to pass on the unspecified inputs to
make-process->cache-prefix.  I’m not sure if we should keep picking
inputs from the environment silently and by default, but your patch is
anyway more correct than what we had before.

Thanks again!
