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.

<h1 align=center>ROGUE 3.6</h1>

<hr>

<h2>NAME</h2>
<blockquote>
	<p>rogue3 &minus; Exploring The Dungeons of Doom</p>
</blockquote>

<h2>SYNOPSIS</h2>
<blockquote>
	<p><b>rogue3</b> [ -s ] [ <i>save_file</i> ] [ -n <i>playername</i> ]</p>
</blockquote>

<h2>DESCRIPTION</h2>
<blockquote>

	<p align="justify"><u>Rogue</u> 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.</p>

	<p align="justify">To get started you really only need to know two commands. 
	The command ? will give you a list of the available commands and the command /
	will identify the things you see on the screen.</p>

	<p align="justify">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.</p>

	<p align="justify">When the game ends, either by your death, when you quit, 
	or if you (by some miracle) manage to win, <u>rogue</u> 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.</p>

	<p align="justify">For more detailed directions, read the document <u>A Guide 
	to the Dungeons of Doom</u>.</p>

</blockquote>

<h2>OPTIONS</h2>
<blockquote>

	<p align="justify">If a <i>save_file</i> argument is given, <u>rogue</u> will attempt 
	to load  a  previously saved game from that file.</p>
	<p align="justify">With  the  <b>-n</b>  option,  <u>rogue</u> will load a game with the 
	name <i>playername</i> from a location defined at compile time.  If no such
	game  exists,  it will start one.</p>
	<p align="justify">The <b>-s</b> option prints the top-ten scores list and exits.</p>
</blockquote>

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.</p>
