Regardless, my point is that "as with word splitting" is not exactly true,
and misleading statements
have no place in documentation if it's meant to be of any use to a user who
needs the documentation
to begin with.

In any case, adding "A backslash can be used to escape a delimiter or a
newline." shouldn't make
the text significantly heavier, given it already uses almost double the
letters to spell out how the words
are assigned to the names given in order.
