[NTG-context] index formatting

Hi all, there is a problem with index formatting (I'm using the latest beta, but have no idea if this was always the case or has been introduced recently). My index is in two columns (the default, I believe). If an item has several references, the lines doesn't break, but continues into the margin or into column 2. Lines do break after the en-dash at index ranges, so it looks like the space after the comma is non- breakable. It's difficult to make a minimal example for that, but what I see is this: Virgil 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 instead of Virgil 1, 2, 3, 4, 4, 6, 7, 8, 9, 10, 11, 12, 13 Best Thomas
