diffstat 1.49
improve lzma support, add support for xz (patch by Eric Blake).
add special case for no-newline message from some diff's (Ubuntu
#269895).
improve configure check for getopt header.
add configure special case for HPUX 11 with _XOPEN_SOURCE definition.
update config.guess, config.sub
11-Aug-2009
diffstat 1.48
add decompression tests for lzma and pack file types.
check for zcat and uncompress in preference to "compress -dc".
modify to check the first few bytes of standard input, and use a
corresponding decompression utility if the stream appears to be
compressed. This requires making a temporary copy of the data
(Debian #491575).
add -N option, to truncate filenames.
use getc_unlocked() rather than fgetc_unlocked()
modify to recognize Perforce-style diffs (patch by Ed Schouten).
update configure macros to improve compiler warning checks, use
$PATH_SEPARATOR rather than $PATH_SEP (for consistency with some
autoconf versions),
fix typo in configure --with-install-prefix option (report by
Dagobert Michelsen).
update config.guess, config.sub
29-Mar-2009
diffstat 1.47
modify to work with patch ".rej" files, which do not have a header to
tell which file is affected.
fix typo in usage message (reports by Moritz Barsnick, John McNamara,
Richard Quadling).
Changes:
* add "-S", "-D" and "-m" to provide a way to show the amount of
difference relative to the total sizes of the files.
* add "-q" (suppress the "0 files changed" message for empty diffs)
From changelog:

diffstat 1.45
add "-b" option (Debian #379380, patch by Greg Norris).
26-Aug-2007
diffstat 1.44
add a check for default-diff output, e.g., "diff foo bar|diffstat",
which has no "diff" command in the output for diffstat to guess that
a diff is beginning.
add a check after completing a chunk for unified diff to ensure that
the next line either begins another chunk for the diff, or starts
another diff, e.g., a context diff (report by Adrian Bunk).
add configure options for leak-checking valgrind, etc.
use install-sh rather than install.sh
updated config.guess and config.sub
updated configure macros CF_GCC_ATTRIBUTES CF_GCC_WARNINGS CF_MSG_LOG
CF_PATH_SYNTAX CF_VERBOSE CF_XOPEN_SOURCE
Changes since 1.41:
- fix to avoid modifying data which is being used by tsearch() for
ordering the binary tree (report by Adrian Bunk).
- do not ignore pathnames in /tmp/, since some tools create usable
pathnames for both old/new files there (Debian #376086).
- correct ifdef for fgetc_unlocked().
- updated configure macros CF_GCC_VERSION, CF_PATH_SYNTAX and
CF_XOPEN_SOURCE
- add configure check for compress, gzip and bzip2 programs that may be
used to decompress files.
* add options -l, -r and -t. add to -f option
* improve I/O on Linux using fgetc_locked().
* improve searching of long sorted lists using tsearch()
* change order of merging and prefix-stripping so stripping all prefixes,
e.g., with -p9, will be sorted as expected
* correct a reference to freed memory after merging found with valgrind.
* fix a different case for data beginning with "--" which was treated as
a header line.
* Fix allocation problems. Open files in binary mode for reading.
Getopt returns -1, not necessarily EOF. Add const where useful. Use
NO_IDENT where necessary. malloc() comes from <stdlib.h> in standard
systems
* minor fix for resync of unified diffs checks for range (line beginning
with '@' without header lines (successive lines beginning with "---"
and "+++")
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
* Improve check for certain lines (not those that begin a chunk) that
begin with '-', treating all except "---" as a delete (report by
James Rowe <Jay@jnrowe.uklinux.net>).
* Minor updates to configure script.
From the readme:
This program is a simple filter that reads the output of the 'diff' program,
and produces a histogram of the total number of lines that were changed. It is
useful for scanning a patch file to see which files were changed.
