The convention to calling into built-in command implementation has been updated to pass the repository, if known, together with the prefix value. * jc/pass-repo-to-builtins: add: pass in repo variable instead of global the_repository builtin: remove USE_THE_REPOSITORY for those without the_repository builtin: remove USE_THE_REPOSITORY_VARIABLE from builtin.h builtin: add a repository parameter for builtin functions
