SourceBuffer.beginNotUndoableAction

Marks the beginning of a not undoable action on the buffer, disabling the undo manager. Typically you would call this function before initially setting the contents of the buffer (e.g. when loading a file in a text editor). You may nest gtk_source_buffer_begin_not_undoable_action() / gtk_source_buffer_end_not_undoable_action() blocks.
