100 lines

Here’s a geeky puzzle for you. The mission: Using only combinations of Copy and Paste, create exactly 100 iterations of a given line of text. Deleting excess lines (>100) is not allowed, nor is typing the 100 lines manually. What is the fewest number of Copy+Pastes needed to achieve the 100 lines?

I’ve got it down to nine Copy+Pastes. How about you?

Update

Looks like seven copy+pastes is the current contender. And since someone asked, the first line doesn’t count against your total (in other words, assume the first line is already there). Here are two different ways to get seven:
