doc maintainer questions

[David Wohlferd]

I have been discussing adding some content to the basic asm docs. As 
part of this work, I want to add a discussion of "How to convert basic 
asm to extended asm."  However it doesn't seem like this is a good fit 
for the User Guide.  This is both because the UG doesn't generally talk 
about "How To" write code, and because the text may need updates more 
often than the UG gets released.

I'm thinking this might be a better fit for the gcc wiki.  But that 
brings up a few questions:

1) Is it appropriate for the UG to link to sections in the wiki?  I see 
that we do, but should we?
2) How do I get 'edit' access to the wiki?
3) Where in the wiki should it go?
