We keep a static array of variables that should be cleared when invoking a sub-process on another repo. We statically size the array with the LOCAL_REPO_ENV_SIZE macro so that any readers do not have to count it themselves. As it turns out, no readers actually use the macro, and it creates a maintenance headache, as modifications to the array need to happen in two places (one to add the new element, and another to bump the size). Since it's NULL-terminated, we can just drop the size macro entirely. While we're at it, we'll clean up some comments around it, and add a new mention of it at the top of the list of environment variable macros. Even though local_repo_env is right below that list, it's easy to miss, and additions to that list should consider local_repo_env.
