Did that -- I tried again with -Q, after having moved ~/.emacs.d/elpa to
~/.emacs.d/elpa.hid.

I then of course had to M-x list-packages RET and install ivy again; that
turned out to get me ivy-0.12.0, so I updated the repro.el file to reflect
that, then started over (with -Q of course); it did just the same thing.

I started over, this time using the same git commit as the system which
worked -- that failed too! So it's clearly not emacs.  I noticed that on
the system that worked, "man -k ." yielded about 14000 lines of output,
whereas on the system that failed, the same command yielded ".: nothing
appropriate" ... so it's pretty likely that my "man" command is at fault,
not Emacs.
