--Silently corrected some typos (note that the German included archaic
and modern spellings both.)
--Corrected the alphabetical order in the index of first lines, and
restored one missing entry.
--Consistently included author and date on the same line, right justified
(the date had often been on a separate line)
--Consistently included scripture references on the next line, right
justified (some had been on the same line after a dash.)
--Re-ordered pages to present each hymn (German and English) as a unit
(the original showed German and English interlaced on facing pages.)
--Note that there is no source information about anonymous hymns in the
original book.
