FAQ change, final draft

[Robert J. Hansen]

> Hi Robert, This looks great. One very minor point (possibly not

No, because that's the first time anyone's asked that question on the 
list -- so it's not a frequently asked question.  :)

> What is GPG planning as the default curves? NIST, Brainpool or ?

Beats me, you'd have to ask Werner, I have no involvement with the code, 
and I can't even tell you which curves I'd personally recommend.

Due to my father being a U.S. federal judge, I think a lot of the GnuPG 
community would react very badly to me ever touching the GnuPG code.  In 
deference to their wishes, I limit myself to maintaining the FAQ and 
answering routine questions.  "Which curves will we use and why?" is not 
within my remit.  :)
