Should respect XDG for user hooks #36
Description
https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
The XDG basedir spec outlines the guidelines for applications and tools to store configuration, data, and cache files in a consistent, and user-configurable manner. This specification is aimed at Linux distributions but is 100% compatible with mac and windows as all the variables are derived and default from $HOME (which exists and is specified for both mac and windows).
git itself respects XDG (it respects the config file at $XDG_CONFIG_HOME/git/config)
TL;DR: git-hooks should look for user hooks under ${XDG_CONFIG_HOME:-$HOME/.config}/githooks/ and not ~/.githooks
