Ok, I've tried this out with my app in the sandbox. I can confirm that
opening a file dialog (NSSavePanel underneath), with a directory pointing
to the Container's Documents directory
(/Users/nick/Library/Containers/my.app/Data/Documents), will show the
standard Mac file selection dialog with the standard ~/Documents directory
selected. If you then select a file there, say 'selected-file.txt', click
OK, the dialog will return the path ~/Documents/selected-file.txt.  Since I
have the com.apple.security.files.user-selected.read-write entitlement in
my application, I can subsequently write to this path, and the file is
written in ~/Documents/selected-file.txt, not in the Container's Documents
directory.

So this clears up my questions about this patch. Thanks for helping me
through it.

Cheers,
Nick
