Make 2004/burley fix more like original

The code can recursively call main() as long by changing the name of the
argv and by a cast in the call.

Updated Makefile to disable a new warning.

Improved index.html file.

 This is a [draw poker](https://en.wikipedia.org/wiki/Draw_poker) program.  You
 start with $100.  Input alternates between your bet and which cards to keep.
-Example:
 
-```
-    5           <== you enter a bet of $5 (defaults to $1)
-    J Q J 9 5   <== your hand is Jack of Clubs, Queen of Hearts,
-    C H D S C       Jack of Diamonds, 9 of Spades, 5 of Clubs
-    123         <== you enter which cards you want to keep
-                    (enter 0 to 5 digits between 1 and 5)
-    J Q J J Q   <== your new hand is Jack of Clubs, Queen of Hearts,
-    C H D S C       Jack of Diamonds, Jack of Spaces, Queen of clubs
-    $145 (45)   <== Your new balance is now $145.  You had a Full House
-                    so your payoff is 9 times your bet == 45
-```
+### Example:
+
+Here is an example.
+
+First, enter your bet (say `5`) (for $5, defaults to $1). You might then see
+something like:
+
+> J Q J 9 5<br>
+> C H D S C
+
+That indicates your hand is Jack of Clubs, Queen of Hearts, Jack of Diamonds, 9
+of Spades and 5 of Clubs.
+
+Now enter what cards you want to keep (enter 0 to 5 digits between 1 and 5).
+Let's say you want to keep 1, 2 and 3 so you enter `123`. You should see
+something like the following after you hit enter:
+
+> J Q J J Q<br>
+> C H D S C
+
+which tells you that your new hand is Jack of Clubs, Queen of Hearts, Jack of
+Diamonds, Jack of Spaces and Queen of clubs. You might now see something like:
+
+> $145 (45)
+
+which tells you that your new balance is now $145. You had a Full House so your
+payoff is 9 times your bet == 45.
+
+#### Payout:
 
 The payout is according to "Vegas rules":
 
-```
