Thanks! It appears to fix the issue with notmuch.

However, I noticed a different problem introduced by the patch.

After executing 3, if I run M-x describe-text-properties, the overlay is
not listed in the text properties. Running
M-: (overlays-in (point-min) (point-max)) does list the 0-length
overlay 5..5. However, running M-: (overlays-at 5) yields nil.

I think that the above is not right.
