You have to call tex.ligaturing too, because ligatures may change 
hyphenation. And you might get special kinds of disc nodes. See section 
6.5 of the manual.

In the second case you can specify "global", whereas in the first case 
the assignment is necessary local. So in some cases the function 
approach is the only one that'll work.
