I am inserting the database entry into the buffer, but because `set-auto-mode' works only on buffers with associated file names, I am assocating a file name with revision number. This association makes buffer look modified and killing buffer asks for saving. I would like to tell that buffer is not modified, as the information arrived from database and it is anyway in a read only mode.
