[PATCH] btrfs-progs: don't overrun "answer" array in cmds-chunk.c

[Eric Sandeen]

If an array is 5 chars in size:

       char answer[5];

and we write the 6th char (counting from 0)...

       answer[5] = '\0';

we get problems:

cmds-chunk.c: In function 'ask_user.clone.0':
cmds-chunk.c:1343: warning: array subscript is above array bounds

Fix it...
