endsLine

Returns true if @iter points to the start of the paragraph delimiter characters for a line.

Delimiters will be either a newline, a carriage return, a carriage return followed by a newline, or a Unicode paragraph separator character.

Note that an iterator pointing to the \n of a \r\n pair will not be counted as the end of a line, the line ends before the \r. The end iterator is considered to be at the end of a line, even though there are no paragraph delimiter chars there.
