- visual feedback after a prompt: append an empty line to the message
window when clear_nhwindow(WIN_MESSAGE) is called. Filter
out empty lines in the buffer except for the active slot.
- append ellipses to the status line text if the text is truncated
- get rid of message boxes at the end of the game (ignore empty lines in
raw_print as Yitzhak suggested)
Add absent prototypes to some core routines.
Also add some port function() to function(void) in some win32 routines.
Also updates the Borland C Makefile for win32.
