curses message history vs dumplog message history

When I implemented getmsghistory()/putmsghistory() for curses I was
assuming that DUMPLOG would only be used with tty, but it is interface
neutral and can be used with curses (or others).  So curses message
history needs to behave like tty message history and be sure to pass
along messages that bypass pline() and the normal message window.
(Mainly one-line summaries of long quest messages, but also old
messages fetched from a save file and available to be re-saved without
having been shown if new session doesn't generate enough new messages
to flush them.)
