Change the hardcoded lookup for .git/hooks/* to optionally lookup in
$(git config core.hooksDirectory)/* instead if that config key is set.
This is essentially a more intrusive version of the git-init ability to
specify hooks on init time via init templates.
The difference between that facility and this feature is that this can
be set up after the fact via e.g. ~/.gitconfig or /etc/gitconfig to
apply for all your personal repositories, or all repositories on the
system.
I plan on using this on a centralized Git server where users can create
arbitrary repositories under /gitroot, but I'd like to manage all the
hooks that should be run centrally via a unified dispatch mechanism.

DESCRIPTION
-----------
-Hooks are little scripts you can place in `$GIT_DIR/hooks`
+Hooks are little scripts you can place in the `hooks`
directory to trigger action at certain points. When
'git init' is run, a handful of example hooks are copied into the
`hooks` directory of the new repository, but by default they are
all disabled. To enable a hook, rename it by removing its `.sample`
suffix.
+By default the hooks directory is `$GIT_DIR/hooks`, but that can be
+changed via the `core.hooksDirectory` (see linkgit:git-config[1]).
+
NOTE: It is also a requirement for a given hook to be executable.
However - in a freshly initialized repository - the `.sample` files are
executable by default.
