Adding the comments to the .config files sounds like a good project for a 
comparative newbie. By the end of next week I should have hardware available 
for experimental kernel builds. (And also some free wetware cycles.) 

Are there any other requirements for formatting I should consider? 

In a case where option A is specified by option B which is specified by option 
C which is specified by option D, should the comment on A mention B, or D or 
all three items in the chain?
