[.txt] Problems when deleting several consecutive lines

[berrymot]

(1) A description of the issue. A screenshot is often helpful too.
(2) A copy of what you're diffing. If you're diffing files, include the before and after files. If you're using difftastic with a VCS repository (e.g. git), include the URL and commit hash.

I deleted the first 135 lines of Xextan/vlabuk/words.txt (commit, hash 2f52564fc8115e410c000cd17776b4ad8be36e03). Despite this, Difftastic shows me only this for that file:

Line 3 was not kept, old line 136 is unchanged and therefore shouldn't be green, and there was no gap to explain splitting the diff into two parts.

(3) The version of difftastic you're using (see difft --version) and your operating system.
