Trailing whitespace can easily get lost

The comment above the assingment spell the character names out for
that exact reason.  Honestly, I think

IFS=' ''	''
'

is a lot harder to read.  If we were writing in bash, we would
probably use $' \t\n' but because we aren't, the best you can do
with your approach is what you wrote, but it would make the reader
wonder what these empty '' are there for and how many spaces are in
between the ''<string here>'' pair.

In other words, I agree with your concerns, but I do not think your
rewrite helps very much.
