PDCurses does not restore some console mode flags correctly on Windows

[vyv03354]

Since GetConsoleMode does not return ENABLE_EXTENDED_FLAGS (0x0080),

GetConsoleMode(pdc_con_in, &old_console_mode);
SetConsoleMode(pdc_con_in, SP->_trap_mbe ?
               (ENABLE_MOUSE_INPUT|0x0088) : (pdc_quick_edit|0x0088));
SetConsoleMode(pdc_con_in, old_console_mode);

will not preserve ENABLE_INSERT_MODE and ENABLE_QUICK_EDIT_MODE (if SP->_trap_mbe is true).

I hit this bug when I used chistedit curses UI that Mercurial 4.9 introduced. Everytime I run hg histedit, I have to re-enable Insert mode and QuickEdit mode from the Properties dialog.
