Confirmed. The bug is with this bash release. I downloaded and compiled ftp://ftp.gnu.org/pub/gnu/bash/bash-2.04.tar.gz (presumably close enough to the RedHat-modified version you used), it has the bug that ./bash -c 'set a b; sIFS=$IFS; IFS=-; h=$*; IFS=$sIFS; echo "$h"' outputs 'a b' rather than 'a-b'. This bug has been fixed in ftp://ftp.gnu.org/pub/gnu/bash/bash-2.05.tar.gz OK to apply this documentation update?
