* 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.
