It is indeed, setting DISP_INFINITY to 1000000000 "fixes" that bug. 
But... how infinite is infinite?  (A near-philosophical question 😉) 
With a somewhat larger file (that one is only 20 MB) we'd have to increase 
it again.  If that's a hard-coded limit, I guess it's a sign that we 
should advise against using toggle-truncate-lines in buffer with long 
lines.
