Subject: [PATCH] Resolve bug/not a bug status in 1995/cdua

What was once thought to be a bug or possible bug is actually a feature.
With a more lucid head I see that in a certain condition (which I noted
in bugs.md) it very clearly is intentional that one should have to hit a
key (it says return as '<RET>' but it uses getchar() via the pointer
'm'). The condition is !(g-a). I do not know the purpose of it but
INABIAF and so should not be changed.

Thus it's not a possible bug or bug but a feature. This is noted also in
the README.md file.

 This did not originally compile under macOS and after it did compile under
 macOS, it crashed. [Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson)
 fixed these problems.
 
-However he observed that sometimes the program asks the user to hit return a
-second time to resume solving the maze. It does not always happen. It doesn't
-seem to be related to making it work under macOS as all that did was removing
-some invalid prototypes and use `printf()` instead of the invalid pointer to it
-(incompatible type). Besides that it happened under linux where there was no
-compilation error or crash.

-It's possible this is no longer an issue but if it's encountered again please
-let us know or offer a fix.
+It should be noted however that there is a condition where the program will
+prompt you to press return again. This was thought to be a bug but looking at
+the code it can clearly be seen that if `g - a` is 0 then the message is
+supposed to be printed again and one is supposed to press a key as at that point
+it calls `getchar()` via the pointer `m`. So this is a feature not a bug.
