When you set a variable hook (grub_register_variable_hook), this hook isn't preserved after someone (e.g. configfile command) opens a new context (grub_env_context_open), unless the variable has been set as global (grub_env_export).
Is this what we want? The only current user of variable hooks is "root" variable, and that hook contains a sanity check that seems to be more suitable for global scope. The color-related variables for which I wanted to add hooks would also like to keep their hooks across contexts. One option is to export these variables, or to modify grub_env_context_open() to preserve hooks as well as exported variables. I'm more inclined for the latter.
