This results in 5 in bash, ksh, older dash, yash, everything I can think 
to test. Whitespace IFS characters is meant to be handled differently 
from non-whitespace IFS characters, I think 5 is the correct result.

But with IFS=": " instead of IFS=:, the output was previously 4, is 
supposed to be 4, and has changed to 2; I agree that it looks like dash 
has introduced a bug here.
