> nit: initialisation is not necessary

heh, I knew I missed something :) it's not a nit IMHO, static analysis
tools could complain about it.

What I usually do to avoid such situations: declare it inline with the
code and `const`, e.g.

char *const p = extract_programmer_param("type");

This way it's clear that it can never be used unitialized.
