[fetchmail]imap 'read' mark issue?

... interesting ... I have just seen the same group of pieces pulled
in multiple retrieval sessions, using fetchmail 5.8.9 ... It appears
not to be committing 'read' marking at the remote end using imap
retrieval, when the session is through an SSH tunnel, and terminates
before normal completion.

This seems to be new behaviour compared with 5.8.4, to which I have
fallen back.

I am building current (5.8.10), and I will see if it persists.
