That's the test whether the math cursor is within a particular cell in a
larger formula.
So if we want only to preview full math insets, we'd use the test from
the previous mail. If we, however, also want to preview bits of a large
formula that are not currently being edited (like the n*m-1 'other'
cells of a big table), we'd ise this test here.
But I don't think the partial previewing work right now.
