} They're not actually in competition; I meant to ensure it was possible
} to specify both, which I've done.

I think Mikael is asking about specifying both conditions in the *same*
glob pattern, i.e. **/*~*/foo~*/bar(Y-) such that bar directories are
short-circuited whereas only paths ending in foo are excluded, but any
files below a directory foo remain.  Your doc and the comments about
treating multiple ~ as if they were | seem to imply that both foo and
bar would be short-circuited in this example.

Of course one can still write **/*~*/foo~*/bar/* without (Y-).
