Fixes #197 Fixes #195 Add a call to nonl() to tell curses not to convert carriage return (^M) to newline. Line input accepts both ^J and ^M as end of line/end of input, but the core's command processing treats ^M as "unknown command" (by default; someone could use the BIND option to assign some command to that character). The end result is that accidentally pressing the <return> or <enter> key (or Ctrl+M key combination) won't make the hero run towards the bottom of the screen as if the user had typed ^J. The curses docs also claim that it allows more optimization during screen updating by making ^J work as plain linefeed rather than ^M^J newline. The tty interface can achieve this (the 'do not convert ^M to ^J part', not the 'more optimization' part) by issuing the command 'stty -icrnl' (on Unix or sufficiently Unix-like system) prior to running nethack, but that has no effect when using the curses interface (at least with ncurses on OSX where I've tested it). A better fix would be to look up the current terminal settings at program startup and only call nonl() if -crnl was in effect so that curses and tty would behave the same in this regard, but curses is supposed to let us avoid those sorts of messy details....
