find a cleaned up 'ge' script below.
and please fix gitXnormid.sh to simply echo nothing and return with a -1
exit value when a nonsensical ID is passed to it. Right now the output
is quite ugly if you do 'ge blah'.

#!/bin/bash
usage ()
{
echo 'usage: ge <commit-ID>'
exit -1
}
if [ $# != 1 ]; then
usage
fi
ME= $(commit-id $1); [ "$ME" = "" ] && usage
PARENT=$(parent-id $ME); [ "$PARENT" = "" ] && usage
TREE1= $(tree-id $ME); [ "$TREE1" = "" ] && usage
TREE2= $(tree-id $PARENT); [ "$TREE2" = "" ] && usage
cat-file commit $ME
echo
git diff -r $TREE2:$TREE1
