setImplicitTrailingNewline
Sets whether the @buffer has an implicit trailing newline.
If an explicit trailing newline is present in a class@Gtk.TextBuffer, class@Gtk.TextView shows it as an empty line. This is generally not what the user expects.
If @implicit_trailing_newline is true (the default value):
when a class@FileLoader 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 class@FileSaver 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.
Parameters
implicitTrailingNewline
the new value.
