Kerning of doxology (and in general)

[MRoth1910]

When looking at #20, it became apparent that the doxology was copied from an earlier iteration.

Having a file with the kerned (so, hspace*) text for each mode/differentia psalm .tex file for EB Garamond may be helpful.

but comments here would be OK in the meantime if you see that there are contradictory modifications (or one file without any) between two different .tex files for the same mode/ending.
