Fix some terribly depressing corruption during restore.
In rogue5/state.c, rs_read_daemons() zeroes out the argument and delay
if the daemon slot is empty. Unfortunately that code ended up on the
wrong side of the brace that closes the for loop, so instead of running
after each daemon, it got run once after the loop exited, when the
index was of course out of bounds.
This tended to manifest, when compiled with -O2, by overwriting hw and
setting it to NULL. When inventory() next ran, hw would be passed to
wgetch(), which returns ERR when it gets a NULL argument. This made
md_readchar() think something was wrong and autosave the game.
Upon investigation, rogue3 was found to commit the same mistake.
rogue4 and srogue don't zero the data. arogue5 already does it
properly.
Someday I am going to run all this through Valgrind. Someday when I
am a kinder person who will not be driven to invoke hordes of trolls
and centaurs upon the original authors.

.TH ROGUE 6 .UC .SH NAME rogue \- Exploring The Dungeons of Doom .SH SYNOPSIS .B @PROGRAM@ [ -s ] [ .I save_file ] [ -n .I playername ] .SH DESCRIPTION .PP .I Rogue is a computer fantasy game with a new twist. It is crt oriented and the object of the game is to survive the attacks of various monsters and get a lot of gold, rather than the puzzle solving orientation of most computer fantasy games. .PP To get started you really only need to know two commands. The command .B ? will give you a list of the available commands and the command .B / will identify the things you see on the screen. .PP To win the game (as opposed to merely playing to beat other people's high scores) you must locate the Amulet of Yendor which is somewhere below the 20th level of the dungeon and get it out. Nobody has achieved this yet and if somebody does, they will probably go down in history as a hero among heros. .PP When the game ends, either by your death, when you quit, or if you (by some miracle) manage to win, .I rogue will give you a list of the top-ten scorers. The scoring is based entirely upon how much gold you get. There is a 10% penalty for getting yourself killed. .PP For more detailed directions, read the document .I "A Guide to the Dungeons of Doom." .SH OPTIONS .PP If a .I save_file argument is given, .I rogue will attempt to load a previously saved game from that file. .PP With the .B -n option, .I rogue will load a game with the name .I playername from a location defined at compile time. If no such game exists, it will start one. .PP The .B -s option prints the top-ten scores list and exits. .SH FILES .ta 2i @SCOREFILE@ Score file .br ~/rogue3.save Default save file .br @SAVEDIR@ System savefiles .DT .SH SEE ALSO Michael C. Toy, .I "A Guide to the Dungeons of Doom" .SH BUGS .PP Probably infinite. Currently known bugs are: Sometimes you are still hungry even after you eat food and sometimes you get a monster on the screen in reverse video which may or may not cause a core dump. .SH COPYRIGHT Rogue: Exploring the Dungeons of Doom .br Copyright (C) 1980, 1981 Michael Toy, Ken Arnold and Glenn Wichman .br All rights reserved. .br License: 3-clause BSD, see LICENSE.txt for details.
