ash: [EXPAND] Split unquoted $@/$* correctly when IFS is set but empty
Upstream commit:
Date: Wed, 8 Oct 2014 15:24:23 +0800
[EXPAND] Split unquoted $@/$* correctly when IFS is set but empty
Currently we do not field-split $@/$* when it isn't quoted and IFS
is set but empty. This is obviously wrong. This patch fixes this.
