えー、ヒッジョーにアホ臭い話なのですが、仕事でやってるWordPress案件をVCCWで回してまして、VCCWで自動生成されるコードを.gitignoreに追加してなかったので追加したら1,015,563行の削減ができたことをお知らせします。
最初は
.DS_Store
.ansible
.bundle
.envrc
.github/
.idea/
.travis.yml
.vagrant
npm-debug.log
package.box
playbook.retry
/wordpress/.htaccess
/wordpress/sitemap.xml
/wordpress/sitemap.xml.gz
/wordpress/wp-config.php
/wordpress/wp-content/advanced-cache.php
/wordpress/wp-content/backup-db/
/wordpress/wp-content/backups/
/wordpress/wp-content/blogs.dir/
/wordpress/wp-content/cache/
/wordpress/wp-content/upgrade/
/wordpress/wp-content/wp-cache-config.php
/wordpress/wp-content/ai1wm-backups
