Update to 1.56:

2013/02/11 (diffstat 1.56)
	+ add -K option which attempts to improve the annotation of "only"
	  files by looking for a match in the resulting set of files and
	  inferring whether the file was added or removed (request by Marc
	  Haber).

	+ add check of command-line options for valid numbers.

	+ improve merging of patches for the same filename (report/testcase by
	  Paul E McKenney).

	+ document -d option in manpage.

	+ document -b, -C, -s option in usage (patch by Tim Waugh, Red Hat
	  #852770)

	+ modify configure script as done for byacc in 2012/10/03, making the
	  2.52-patches the prerequisite and adding support for --datarootdir
	  option.

	+ update config.guess, config.sub

	+ add logic to handle SVN diffs when the pathnames contain spaces
	  (patch by Stuart Prescott, Debian #675475).

	+ fix typo in package/debian/control

2012/01/03 (diffstat 1.55)
	+ add -R option, like patch's, to reverse the order of the comparison.

	+ FreeBSD ports/148604, ports/149500 reported that lzcat may not
	  support extracting files compressed in xz format (patch by Frederic
	  Culot, FreeBSD #149500).

	+ address documentation issue raised in Novell #739210

	+ correct typo s/Solaris/Solar/.

	+ updated configure script macros:
	  CF_ANSI_CC_CHECK CF_DISABLE_LEAKS CF_GCC_ATTRIBUTES CF_GCC_WARNINGS
	  CF_MAKE_TAGS CF_MSG_LOG CF_PATH_PROG CF_WITH_INSTALL_PREFIX
	  CF_XOPEN_SOURCE

	+ update config.guess, config.sub

2010/10/10 (diffstat 1.54)
	+ change Debian package script to use native format.

	+ correct counts used for new files when -S/-D options are used.

	+ minor typography improvement to manpage (patch by Solar Designer)

	+ remove the temporary directory on error, introduced in 1.48+ (patch
	  by Solar Designer).

2010/07/19 (diffstat 1.53)

	+ add missing "break" statement which left "-c" option falling-through
	  into "-C".

2010/07/16 (diffstat 1.52)

	+ add "-C" option to show the histogram using SGR colors.

	+ add "-s" option to show only the summary line.

	+ add configure check for "xz", using this in preference to "lzcat"
	  (FreeBSD #148604).

	+ also escape literal dashes used as part of the histogram in the
	  manpage.

	+ modify hyphens vs dashes in manpage per
		http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html
	  (patch by Francois Marier).

	+ drop mkdirs.sh, use "mkdir -p"

	+ add configure checks for ctags and lint.

	+ updated configure macros

	+ reformat CHANGES to work with metrics script.

	+ fix strict gcc warnings, e.g., using const.

	+ improve a case where filenames have embedded blanks (patch by Reinier
	  Post).

	+ update config.guess, config.sub
