Ah, thank you for the information. I have been somehow wrongly
thinking that this special treatment would only happen when IFS has
the default value. I think I was confused by the description in "man
bash" about the treatment of the consecutive whitespaces at the
beginning and the ending of the string. I haven't noticed this
behavior so far since I usually use ":", ",", etc. as the delimiter
for my codes.
