  Several fixes to the extenpatternmatchnew logic.

  1. Differentiate between literal characters in an extension
  and characters that should be treated as a pattern match. Prior to
  these fixes, an extension such as NNN would be treated as a pattern,
  rather than a literal string of N's.

  2. Fixed the logic used when matching an extension with a bracketed
  expression, such as 2[5-7]6.

  3. Removed all areas of code that were executed when NOT_NOW was
  #defined. The code in these areas had the potential to crash, for
  one thing, and the actual intent of these blocks seemed counterproductive.

  4. Fixed many many coding guidelines problems I encountered while looking
  through the corresponding code.

  5. Added failure cases and warning messages for when duplicate extensions
  are encountered.

  6. Miscellaneous fixes to incorrect or redundant statements.
