The .htaccess settings depend on the development environment, in some cases it is not used.

without leading slash, it ignores all files with these names (cron.php,
get.php, index.php, api.php), whereveer they are

The Magento production is configured to automatically generate the sitemap.xml, as is the url is taken as a base, it is important to be ignored.

Added Configurable Swatches and Pelago lib to ignore list

According to [this](http://www.magentocommerce.com/magento-connect/thefind-feed-1.html) TheFind Feed module does not come with the latest versions of Magento( > 1.6).

Thank you

Magento keeps a log of official patches applied in this file.

The line for `install.php` blocks adding *any* file with that name. In this instance, it caused Git to ignore a file for the Aitoc_Aitsys module located at: `app/code/local/Aitoc/Aitsys/Model/Module/Install.php`
