[ast-developers] Regressions with Null Character

[Siteshwar Vashisht]

Hello,

Patch posted at [1] introduced a regression in ksh with null characters.

Steps to reproduce:

for i in `perl -e 'printf "a%c\nb\n",chr(0)'`; do echo $i; done

Output:
a

Expected Output:
a
b

I am attaching a patch that works around this issue.
