Oh, I see. So yes, it's related: it shows there's a need to keep both the
normal environment and the "environment for the subprocess started by
call/start-process".
For Tramp, it's indeed pretty tricky: the environment to use for the local
process is not the one you receive from process-environment (which is
destined to the remote process) but is rather "the global default
process-environment" (maybe with a few minor adjustments). But this default
process-environment is not quite the same as the initial-environment that
I proposed either (although it can probably get by with just
initial-environment).
