Michael Meyer 2bb73b8fd8 Prevent curses 'More' (>>) from overwriting msg ...

In some scenarios where a message prompted a 'more' (in curses shown as
'>>'), the '>>' could overwrite the last one or two characters of the
message.

This could happen if a single message on its own was the length of the
message space minus 2 (e.g. for an 80 character terminal, "h - a concave
amulet named this is an amulet name, it is very long, and so on."), or
if an addition to an existing line brought it to the length of the
message space minus 1 or 2 (e.g. "You materialize on a different level!
You remember this level as testlevlname.").  The two scenarios had
slightly different causes.

I think this fixes both of those scenarios.  I believe this is the
cause of the problem described in GitHub issue #990 but there isn't
enough detail to know that for a fact.
