[bug-diffutils] I'd like to release 3.3

[Jim Meyering]

Hello,

I want to release diffutils-3.3, primarily to make it so
the latest release is not susceptible to CVE-2012-3386.

Here's the current state of NEWS:

  ** 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.

If anyone has issues for which a release should be delayed,
please speak up.

Otherwise, I'll probably tag the release in the next few days.

As I type this, I'm updating to latest gnulib+bootstrap,
but don't plan any other changes.

Jim
