few new warnings with hush from SVN

[Guenter]

Hi,
just updated to recent SVN, and see now these warnings:

  CC      shell/hush.o
shell/hush.c: In function `expand_vars_to_list':
shell/hush.c:1776: warning: `exp_save' might be used uninitialized in
this function
shell/hush.c:1776: warning: `exp_op' might be used uninitialized in this
function
shell/hush.c:1776: warning: `exp_word' might be used uninitialized in
this function

I did only a quick 1-minute look at the code (and therefore probably
overlooked something), but from that it seems indeed that gcc is right
here...
