The recent POSIX_STRINGS-related change (41499, 2eacbef) introduced at
least one serious bug. I think you should probably revert that commit
before the 5.4 release so it can have more testing before 5.4.1 or
whatever the release after this one is.

$* concatenated, IFS is space:

        emulate sh
        set " abc " " def ghi " " jkl "
        IFS=' '
        set xx$*yy
	echo "$#,$1|$2|$3|$4|$5|$6"

Actual output: 5,xx|abc|def|ghi|jklyy|
Expected output: 6,xx|abc|def|ghi|jkl|yy

The 'yy' is joined to the final 'jkl' instead of becoming a separate
argument.

The same bug happens with $@ (which, when unquoted, acts identically to $*).

Thanks,

- M.
