我的 WordPress 用 1.6，這其實是一條不歸路… (已經沒辦法 downgrade 了 XD)

前幾天升級到 r2735 後發現 write post 時 Categories 部分發生問題：

基於版號是 “1.6-ALPHA-do-not-use” (都已經跟你講不要用了)，於是要 bug report 前先還是去找問題在哪，以及解決的方法… 最後找到是 r2730 產生的問題：

When I upgrade to r2735 (and wp-admin/upgrade.php, of course), I found
there are some PHP warning when I write post:

I trace the code and found it’s because this patch:

I revert this function then it works fine.
