Description:
SPLIT_LINE breaks the current line in two at the current position. If the
current line is blank or the current edit position is after the end of the line, a
new blank line is added. The first character of the new line is moved to the
buffer's left margin position. SPLIT_LINE may cause pad characters to be added.
