Are you saying that I can't backup/restore IFS without setting it
first? That would be odd; it works with bash, dash, and zsh here.
Pointers to affected shell would help me avoid other issues with them.
Alternatively, I could set IFS in a subshell.
I checked the autoconf Portable Shell Programming section, but didn't
find a similar recommendation:

If we go that route, perhaps IFS="`printf ' \t\n'`" would be more
readable? I'm not sure how common printf is though.
