small agent irritation

[Harry Putnam <reader@newsguy.com>]

This is a small gripe that comes up from time to time on my setup.
Not sure of the exact circumstances that bring this on but
occasionally I'll notice a post I want to be downloaded under agent
that has already be read for one reason or anther in `Plugged' mode.

Usually just marking it unread again with `M-u' leaving the group
going plugged and running J u on that group will do it, but
occasionally this does not work.  In the present cast the missing
message is actually in the agentized group as evidenced by
ls ~News/agent....../group/<number>

No amout of redownloading will help this... so I tried to edit
.agentview and .overview for that group.

Adding the file number to .agentview in the same way  others appear:
(16765 . t)

Adding to .overview by inserting the tabs and information as other
files have.  What looks like the normal Nov data.

file#   subject  from  date  message-id  references  charcters  lines

Only with tabs instead of spaces.
Still doesn't show up.  Even `j' with that file number won't find it.
But ls shows it to be on disk, in that group directory.
