Yacine Hmito 1f70f3801b Make zshrc more predictable
Originially, `programs.zsh` sets default values for some
initialisation scripts.
Nix resolves the case of multiple values by concatenating them all.
It is however impossible to predict where the default script will be
inserted; but we never want the default value to override the
user-specified ones.
Now, it doesn't set default values; almost everything is hardcoded at
the begining of the file.
