in FAQ and MANUAL.md

- example.com was made for this purpose.

- reduces the risk that one of those domains suddenly start hosting
  something nasty and we provide links to them

   3.1 curl: (1) SSL is disabled, https: not supported

   This could have happened if the configure script that was run at build time
   could not find all libs and include files curl requires for SSL to work. If
   the configure script fails to find them, curl is simply built without SSL
   support.
