Compare two pastes line by line and mark lines that were removed from the left or added on the right.
A line that appears in both texts is unchanged. A line only on the left is removed. A line only on the right is added. The comparison is the whole line, not a character inside it.
Both texts are split on line breaks. A longest-common-subsequence pass keeps shared lines in order and reports the lines that are not shared.
The result marks an unchanged line with a leading space, a removal with a minus, and an addition with a plus. Each side is limited to 400 lines.
Paste the older text on the left and the newer text on the right.
Read minus lines as removals and plus lines as additions.
If a single word changed, the whole line is reported as removed and added.
alpha is unchanged, beta is removed, and gamma is added.
