display state, i.e., hidden/exposed tags or threads. This fixes at
least two problems:
- If the current message is a duplicate that is deleted by the "deldups"
command, then the dot was invalid making all messages appear to have
been deleted. It is now set to the surviving duplicate message.
- If the current message is tagged, the "hidetags" command would leave
the dot invalid and the dislay would reset it at the top of the
current screen. It is now set the the first untagged (and
not deleted) message after the previous (tagged) dot message.
