All, I mentioned this problem once on the list before; however, the issue wasn't reproducible. Now I found a way to consistently reproduce it.
1. Open a new plain vim in a terminal. 2. ":h" to open a help window. 3. ":wincmd o" to close all other windows except the help window. 4. "G" to go to the last line. 5. "<c-e>" a few times (around 5) to scroll down. 6. ":tab split" to open a new tab. 7. ":tabclose" to close the new tab and return to the previous. After all of this, the space generated by scrolling (via <c-e>) disappears. --Matt
