Subject: TTY: Treat carriage return as newline
X-Git-Tag: NetHack-3.6.1_RC01~213
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=59d4ac02f7737216a54aa3957fe83f22e8a5f7e3;p=nethack

TTY: Treat carriage return as newline

Before this change, more-prompts and input text -prompts could not
be accepted with carriage return. Now, just like in menus, carriage
return is treated the same as a newline.

To test, use 'stty -icrnl'
