I guessed wrong.  And Heirloom nroff behaves differently
from groff.  Some more unexpected behavior can be seen
by shortening the line length to just 1 en.

I also tried the same thing in TeX and learned that by
default TeX doesn't hyphenate the first word of a paragraph.
(I didn't know this before, but I also never yet had to deal
with a document where this was necessary.)

Also interesting to see that in this word, the hyphenation
patterns don't suggest a hyphenation opportunity after "anti".
