I agree for IFS but not for locale vars. I can imagine situations in which an application writer might choose to do that, and the choice would be reasonable. For example, suppose an application has an installation script that needs to validate format strings in a file structured as pairs of lines with the first of each pair containing a locale name and the second containing the format string for that locale. This could be done using code like the following:<pre> unset LANG LC_ALL LC_CTYPE ... export LANG=C while IFS="" read -r LANG do ... validate $LANG ... IFS="" read -r format || ... ... validate $format ... done < file </pre> > if someone really wanted to do: > read LC_CTYPE > all they need do instead is > read var && LC_CTYPE=$var True, but why force them to do that if there's no need? Doesn't my suggestion at the end of https://austingroupbugs.net/view.php?id=1778#c6530 adequately distinguish cases that need to be unspecified from those that don't?
