[BUILTIN] Honor tab as IFS whitespace when splitting fields in readcmd

When I try to split fields by tabs, dash doesn't honour multiple tabs
between fields as whitespace (at least that's how I interpret [1],
please correct me if I'm wrong).

#!/bin/sh

# "1\t2\t\t3"
TESTSTRING="1	2		3"

# only "\t"
IFS="	"
echo "$TESTSTRING" | while read p1 p2 p3; do
	echo "p1=${p1}, p2=${p2}, p3=${p3}"
done
