In that case, you could change the spec by altering the manual from:

"The first line is the directory separator string."


"The first character is the directory separator string."

and probably for the other entries too; and change

"This string is a sequence of lines:"


"This string is a sequence of characters:"

(and remove the newlines!).

That would still be weird, but it would be a distinct improvement.
