replace all tabs with four spaces
The PEAR coding standards decree: no tabs, but indent by four spaces. I've done a global search-and-replace on all tabs, replacing them by four spaces. This is a huge change, but it will go a long way to getting us towards phpcs-compliance. And that means better code readability, and that means more participation. darcs-hash:20081223191907-84dde-21e8efe210e6d5d54e935a22d0cee5c7bbfc007d.gz
