Thanks.  I see no reason why it wouldn't work, and it doesn't crash, so
I've pushed it and am closing the bug.

I did note that buffer_defaults.text changes from NULL to
&buffer_defaults.own_text on the first scan, but this seems harmless to
me.

If these strange objects (no MPS header, these two have a vectorlike
header but buffer_local_flags doesn't, not necessarily lisp-aligned)
cause any trouble, we could always allocate them on the MPS heap, giving
us the very slight benefit of putting some words behind a barrier.

Tracing buffer_local_symbols and buffer_defaults exactly as in
the patch seems to work.
