Subject: [PATCH] Apparently, ReadConsoleInputA() does mistaken sign extension
 to 16 bits, rather than writing only the bottom 8 bits of the decoded key to
 the event structure. PDCurses, in turn, was reading the whole 16 bits even in
 narrow mode, resulting in corrupted "high-bit" characters in wincon.
 Potentially an issue since 3.0 (assuming ReadConsoleInputA() always did
 this?), but seemingly unreported (?) until now. Reported by Simon Sobisch.
