>Description:

When using /bin/sh, setting variables after "|"
(in other words, I mean setting variables in a pipeline sequence),
will be ignored out of the pipeline sequence.

If it is a definition of /bin/sh, it's ok, I'm sorry,
otherwise I think it should be fixed.

>How-To-Repeat:

write a simple shell script like this:
-----------starts here----------
#/bin/sh

cat FILE | while read line ; do
	if [ $line = foo ]; then
		variable=bar
	fi
	echo $variable   <---- this will be printed
done

echo $variable           <---- this will NOT be printed
-----------ends here------------

>Fix:

Sorry, this is only a information of my problem.
