Problem is, you'd have to delete the entries from your history to get rid of them in auto-completion. Safari's auto-completion list = history.
Still, Safari's implementation sucks IMHO:
• Why doesn't it always suggest the most recent item?
• Why do you have to start with the server's ane for an item to appear, for example if I want server.com/list.html and I enter 'list.html' or just 'list' I get nothing; I'd have to enter 'server' or 'server.com' for the entry to show up.
