I think you can change the description to this comparison.

The original opening crawl had the text on 21 lines, so to still keep it as 21 lines when adding two new lines (Episode IV, A NEW HOPE) they simply changed the spacing of the words in the first two paragraphs of the text. That's my theory, but they still didn't get the timing exactly right as the music is now slightly out of sync with the reveal of Tatooine.

Secondly, the capitalization of "Rebel" was not done to match the first (the first Rebel starts a sentence, that's why it has a capital "R") I think it was done to match how it now was written in Empire, I also think they capitalized rebel when they revised the script to ANH in '79.
