Evan Prodromou edbc0c665c 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.
