Author: delphij Date: Mon Nov 9 01:53:54 2015 New Revision: 290569 URL: https://svnweb.freebsd.org/changeset/base/290569 Log: MFC r290024,290073: In gunzip(1), treat trailing garbage as a warning and not an error. This allows scripts to distinguish it between real fatal errors, for instance a CRC mismatch. Update manual page for the behavior change.
