Log Message:
Update to 3.3

Changelog:
* Noteworthy changes in release 3.3 (2013-03-24) [stable]

** New features

  --new-file (-N) and --unidirectional-new-file now allow comparisons to \ 
"-".
  A standard input that's closed acts like a nonexistent file.

  A file name containing spaces, double quotes, backslashes or control
  characters is now encoded in a diff header as a double-quoted C string
  literal.  The escape sequences \\, \", \a, \b, \f, \n, \r, \t, \v and
  \ooo (a three-digit octal number between 0 and 255) are used.

** Packaging

  diffutils is now designed to build with Cygwin or MinGW rather than DJGPP.
  The ms subdirectory has been removed.
