There is one kconfig fix in the rc-fixes branch that I forgot to submit
for 3.8, so let's add it to the kconfig branch for 3.9-rc1.

 NOTE 1:  The multi-line descriptive text you provide does *not* recognize
 line breaks, so if you try to format some text nicely, as in:
 
-  Return codes
+  Return:
     0 - cool
     1 - invalid arg
     2 - out of memory
 
 this will all run together and produce:
 
-  Return codes 0 - cool 1 - invalid arg 2 - out of memory
+  Return: 0 - cool 1 - invalid arg 2 - out of memory
 
 NOTE 2:  If the descriptive text you provide has lines that begin with
 some phrase followed by a colon, each of those phrases will be taken as
 a new section heading, which means you should similarly try to avoid text
 like:
 
-  Return codes:
+  Return:
     0: cool
     1: invalid arg
     2: out of memory
