  Checks if the newly loaded file is write-only in the filesystem. If so, locks the editor with the lock method. Otherwise unlocks the buffer

  For each canvas returned from get-canvases it checks to see if the canvas%'s get-top-level-window matches the frame:editor<%> interface. If so, it calls set-label with the last part of the filename (ie, the name of the file, not the directory the file is in).
