Bingo - I think you now have an all-inclusive definition of what constitutes
a "countable" line. It's a string of 1 or more chars which may or may not
end with a CR.

("Empty" lines come under this definition too, because in reality no line is
empty, even if it doesn't contain display chars - there must be at minimum a
single CR char for there to be an 'empty' line.)

However, CRs are always included in the 'number of characters' count.

Parallel observation:
The counting of lines (with CR as the lineDelimiter) and the counting of
items (with a comma itemDelimiter) work exactly the same regarding number of
things counted, whether or not the last one ends with a delimiter.
