I merged them
Of course. Thanks!
In "Hymns to the Living God" the last line of the verse repeats. It does not do this in 'Lutheran Hymnary" so the last line is highlighted as a difference along with the comma at the end of the previous line because in "Lutheran Hymnary" the line ends with a period. (There may have originally been an extra space inserted at the end of the line in HTLG)
When I edited my original post and added the screenshot, this is what I saw in the editing mode: https://hymnary.org/files/hymnary/image/invisible%20illustration.jpg
But when I saved the edit or published it or whatever it's called, the screenshot was not visible (or even mentioned) in the resulting version of the OP.
I obviously don't know how to post a screenshot here. I added it as a media file and tried to insert it, but nothing shows up. Here's its URL: https://hymnary.org/files/hymnary/image/His%20lips%20with%20grace%20o%27erflow%20but%20how%20do%20they%20differ.jpg
It's Hymns to the Living God and Lutheran Hymnary, not Cyber Hymnal. And I do see that the former ends the line with a comma and the latter with a period, but the apostrophes both look straight to me.
