+- A lone .m2v played with --framefile now finds the .ogg beside it, as a
+  framefile's segments always have.  A Daphne era elementary stream
+  carries no audio of its own, so lair.m2v played silently unless it was
+  listed in a framefile or --altaudio was given.  Any other container
+  keeps using the audio inside it.
+
 - A single-frame image saved as a 1-bit PNG (many overlay assets from
   the 2.x era) loads again; spriteLoad reported "Blit combination not
   supported" on it.  Images with 16 bits per channel or floating point
