Thanks for the report; this is an easy fix.  The fix will be in bash-4.4.

IFS as the control variable in a for loop

2016-05-02 Thread Grisha Levit 
When in a non-interactive shell, IFS, when modified as the control variable
in a for loop does not change splitting behavior.
$ bash -c 'for IFS in .; do printf "%s\n" "$IFS" "$*"; done' bash x x
.
x x

$ bash -ic 'for IFS in .; do printf "%s\n" "$IFS" "$*"; done' bash x x
.
x.x
