 Ok.  I found a place where (false, true) can be used.

 Picture the following table:

    +-----+-----+-----+
    | 0,0 | 1,0 | 2,0 |
    +-----+-----+-----+
    | 0,1 | 1,1 | 2,1 |
    +-----+-----+-----+
    | 0,2 | 1,2 | 2,2 |
    +-----+-----+-----+

 In GTK+, when you attach a widget to a table you specify three
 parameters (expand, fill and shrink) for both x and y.

 Let's say (1,0) has only expand set in x and (1,1) has only fill set in
 x.  The result is that (1,0) expands the whole column and (1,1) has
 more space to fill.  I don't claim this makes sense, I'm only saying
 it's possible.

 After thinking about it, the example I mentioned previously now makes
 sense: a horizontal separator without "fill" set has null size.  But
 you don't want to set expand on it because you want it to be as large
 as the largest element in the group, not larger.

 Now *my* question is what does shrink mean?  Why aren't expand and fill
 enough for a table?  The documentation really doesn't help here.
