Repeated text pasting intersplices text.

[LeifAndersen]

If I have the following buffer:

foo
bar

and I highlight fo, and yank it with y. Then, moving the cursor down to the b on the second line, and pasting with p a few times gives:

foo
bfoafofofofofor

In vim, this should look like:

foo
bfofofofofofofoar

I haven't been able to reproduce this. I added a test case for it. Does it fail for you?
