[PATCH] Better macro error messages involving initializer lists

[Richard Trieu]

  Refactoring the earlier patch to take into account comments.

  - Instead of attempting a correction after every failure, only try after a "too many arguments" failure.
  - Rewrite the code that generates a new vector of token arguments to use the old vector of tokens.  This cuts back the amount of token copying to only when a correction is attempted.
  - Give a note on all arguments started with a brace list instead of only when the brace list is the entire token.
