New Revision: 222735
URL: http://svn.freebsd.org/changeset/base/222735
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.
