Thanks, the fix (in bzr rev 3106) works perfectly here.

From the command line, I can "set pager=1", and then either cat a long file or use a for loop to echo 30 lines, and see that the pager puts up a "-- MORE --" prompt and waits for a key.  However, the same thing doesn't seem to work from within a menuentry in a file loaded by "configfile".  Try putting the following file as "test.cfg" somewhere grub can get at, and then loading it via "configfile /path/to/test.cfg" from the grub command line:

set pager=1

menuentry "Always present" {
    echo Insert something always useful here.
    for x in 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 ; do
        echo Piles of output
    done
}

x=3
if [ "$x" -gt 0 ] ; then
    menuentry "Conditionally present" {
        echo Insert something conditionally useful here.
    }
fi

if [ "$x" -gt 5 ] ; then
    menuentry "Conditionally present (and missing)" {
        echo Insert something conditionally non-useful here.
    }
fi

Loading test.cfg via configfile will bring up a menu with two entries. Choosing either one of them should prompt for a key at the end of the menuentry, and choosing the first one should additionally have a MORE prompt after 24 lines as well as the prompt at the end.

If instead I make that file grub.cfg, rather than loading it via configfile from the command line, then the MORE prompt works in the first menu entry, but I still don't get prompts at the end of each menuentry's output like I did with previous versions of GRUB2.  (I know that it works with at least bzr revision 2587.)
