Bug#486181: grub2: if does not suppress errors from command run as condition

[Josh Triplett]

Package: grub2
Severity: normal

The "if" command does not suppress errors from the command run in its
condition.  For example, this:

if [ 0=1 ] ; then echo t ; else echo f ; fi

will correctly echo "f", but will then print "error: false" and wait
for a key before continuing.  The "if" command needs to suppress this
error.
