You'd think so, right, but ...   and that assumes that the person
writing the printf code (copying the example from the man page) knows
what IFS is, or that it might have been altered.

That, and because it simply is the right way to code in sh 99% of the
time - omitting needed quotes is a major source of bizarre bugs.   When
they're like this, and only trigger in unusual circumstances, they're ever
harder to find.
