If implicit_trailing_newline is true (the default value):
when a classFileLoader loads the content of a file into the buffer,
the trailing newline (if present in the file) is not inserted into the
buffer.
when a classFileSaver saves the content of the buffer into a file, a
trailing newline is added to the file.
On the other hand, if implicit_trailing_newline is false, the file's
content is not modified when loaded into the buffer, and the buffer's
content is not modified when saved into a file.
Sets whether the buffer has an implicit trailing newline.
If an explicit trailing newline is present in a gtk.text_buffer.TextBuffer, gtk.text_view.TextView shows it as an empty line. This is generally not what the user expects.
If implicit_trailing_newline is true (the default value):
On the other hand, if implicit_trailing_newline is false, the file's content is not modified when loaded into the buffer, and the buffer's content is not modified when saved into a file.
