Pandoc bug fixes:

+ LaTeX reader did not parse metadata correctly.  Now the title,
  author, and date are parsed correctly, and everything else in
  the preamble is skipped.
+ Simplified parsing of LaTeX command arguments and options.  
  The function commandArgs now returns a list of arguments OR
  options (in whatever order they appear).  The brackets are
  included, and a new stripFirstAndLast function is provided
  to strip them off when needed.  This fixes a problem in dealing
  with \newcommand, etc.
+ Added a "try" before "parser" in definition of notFollowedBy'
  combinator.  Adjusted the code using this combinator accordingly.
+ Changed handling of code blocks.  Previously, some readers allowed
  trailing newlines, while others stripped them.  Now, all readers
  strip trailing newlines in code blocks; writers insert a newline
  at the end of code blocks as needed.
+ Changed test suite to reflect these changes.
