Subject: [PATCH] Duplicate only current line when cursor is at the end of the
 line (#649)

This fixes issue #643. When cursor is at the end of the line, old
version would duplicate two lines: The line where the cursor is, and the
line following it. This happened because the buffer that is being copied
would include both lines and the newline separating them. This fix
checks if there are multiple lines in the current buffer, and if so,
moves buffers end iterator to the newline character, so that only the
line where cursor is located is duplicated.
