folded-flag for virtual folders

[Uday Reddy]

There is now a folded attribute for messages, which is recorded on the disk. However, virtual folders share their attributes with the underlying folders (when they are mirrored, which is the normal case). How does this work?

Here is a problem case: Create a virtual folder. Go to a root message in the virtual folder, which is not a root message in the underlying folder. Quit virtual folder. When the focus is passed back to the underlying folder, the summary line of the message looks malformed.

The solution is to let the folded flag be as it is, but do actual folding of summary lines only at the root messages.
