Add a new multi-valued config variable "receive.executeCommandsHookRefs" for `receive-pack` command, like the follows: git config --system --add receive.executeCommandsHookRefs refs/for/ git config --system --add receive.executeCommandsHookRefs refs/drafts/ If the specific prefix strings match the reference names of the commands which are sent by git client to `receive-pack`, these commands will be executed by an external hook (named "execute-commands"), instead of the internal `execute_commands` function. For example, if it is set to "refs/for/", pushing to a reference such as "refs/for/master" will not create or update reference "refs/for/master", but may create or update a pull request directly by running the external hook. Use more than one definition to specify multiple prefix strings.
