From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx>
Add a new multi-valued config variable "receive.procReceiveRefs"
for `receive-pack` command, like the follows:
git config --system --add receive.procReceiveRefs refs/for
git config --system --add receive.procReceiveRefs refs/drafts
If the specific prefix strings match the reference names of the commands
which are sent from git client to `receive-pack`, these commands will be
executed by an external hook (named "proc-receive"), 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 hook
"proc-receive".

An attempt to update or delete a hidden ref by `git push` is
rejected.
+receive.procReceiveRefs::
+ This is a multi-valued variable that defines reference prefixes
+ to match the commands in `receive-pack`. Commands matching the
+ prefixes will be executed by an external hook "proc-receive",
+ instead of the internal `execute_commands` function. If this
+ variable is not defined, the "proc-receive" hook will never be
+ used, and all commands will be executed by the internal
+ `execute_commands` function.
+
+ For example, if this variable is set to "refs/for", pushing to
+ reference such as "refs/for/master" will not create or update a
+ reference named "refs/for/master", but may create or update a
+ pull request directly by running the hook "proc-receive".
+
receive.updateServerInfo::
If set to true, git-receive-pack will run git-update-server-info
after receiving data from git-push and updating refs.
