8 Changed FAQs:

• [10.21] Why am I getting an error after declaring a Foo object via Foo x(Bar())?
  (added a new solution thanks to Paul A. Rombouts)
• [16.6] Do I need to check for NULL after p = new Fred()?
  (strengthened the descriptions to clarify that compilers which don't throw on allocation failure are ancient, not just old)
• [16.10] In p = new Fred(), does the Fred memory "leak" if the Fred constructor throws an exception?
  (fixed the "equivalent" code to show that the pointer isn't changed until the ctor succeeds thanks to Michael Cox)
• [18.6] What does "Fred const& x" mean?
  (fixed a copy-error ("pointer" vs. "reference") thanks to Adam Scott, Cameron McCormack, Stefan Pantschitz)
• [18.8] What does "const X& x" mean?
  (fixed a copy-error ("X const&" vs. "const X&") thanks to Adam Scott, Clemens Lode, Cameron McCormack, Mike Leibensperger)
• [18.9] What does "const X* x" mean?
  (fixed a copy-error ("X const*" vs. "const X*") thanks to Adam Scott)
• [18.17] Why am I getting an error converting a Foo** → Foo const**?
  (strengthened and clarified via a new discussion at the end thanks to Miloslavskiy Alexander)
• [26.13] What should be returned from a function?
  (fixed a typo in a code snippet ("const X const*") and two typos in the prose, all thanks to John Dickson)
