Some small progress.

1) I can duplicate the test failure with emacs 25.1 built from source on
   debian testing.

2) I can interactively duplicate a similar, but not identical, bug as
   follows.

   - add the attached message (extracted from the test suite) to my mail
     store
   - open it notmuch-show (emacs 25.1, gtk/GUI)
   - go to the last line of the body. By using C-u C-x =, we can observe
     that the first and third copies of mid:abc are buttonized, but not
     the second.
   - this can also be seen by using the tab button.

3) The bug in 2) seems to be sensitive to the body text. If I delete the
   first 8 body lines, then all of the mid's on the last line are
   buttonized.
