Author: delphij Date: Mon Jun 6 05:48:25 2011 New Revision: 222736 URL: http://svn.freebsd.org/changeset/base/222736 Log: MFC r222210, 222211, 222287: - Diff reduction against NetBSD. The most notable change is to zdiff(1) to handle more file formats including bzip2 and xz. - Match symbolic link handling behavior with GNU gzip, bzip2 and xz: When we are operating on a symbolic link pointing to an existing file, bail out by default, but go ahead if -f is specified.
