Can we change this so that it does this:

    filter_tools () {
    	filter="$1"
    	(
    		cd "$MERGE_TOOLS_DIR" &&
    		for i in *
    		do
    			echo "$i"
    		done
    	) |
        while read tool
    	do
    		setup_tool "$tool" 2>/dev/null &&
    		(eval "$filter" "$tool") &&
    		echo "$tool"
    	done
    }

and keep the sorting and prefix in show_tool_help?  This will make it
easier to integrate the user-configured tools from git-config.
