ignoring an IMAP folder at tab completion

[Thomas Hühn]

Hi

The situation is this:

I have two IMAP folders, "netdigest/submissions" and "netdigest/misc"
which are subscribed.

When I move articles to those folders (B m) I cat type "netd TAB" and it
is completed to "netdigest/".

If I have browsed through all available groups (A A), it is only
completed up to "netdigest", so that my usual key sequence "B m netd TAB
s TAB ENTER" (which comes kind of automatic) fails.

That's understandable, since "netdigest" is a folder of it's own right,
not only "netdigest/submissions" and "netdigest/misc" are.

But "netdigest" is unused here, it is only there for structuring my IMAP
mailbox.

Can I make Gnus ignore the folder-ness of "netdigest" so that it never
considers "netdigest" to be a valid target that should be considered for
tab completion?
