[EXPAND] Free IFS state after here document expansion
Here's another bug bisecting to f42e443bb ([EXPAND] Fix
ifsfirst/ifslastp leak, 2010-09-08). It was found with the following
test case, based on the configure script for Tracker:
dash -x -c '
<<-_ACEOF
$@
_ACEOF
exec
' - abcdefgh
+
+ exec �a
exec: 1: : Permission denied
The missing ifsfree call is in expandarg when it returns to openhere
during here document expansion.
