Author: mm Date: Wed Dec 21 15:30:49 2011 New Revision: 228776 URL: http://svn.freebsd.org/changeset/base/228776 Log: Merge FreeBSD changes from usr.bin/tar to contrib/libarchive/tar: r204111 (uqs): Fix common misspelling of hierarchy r207786 (kientzle): Various manpage updates, including many long-option synonyms that were previously undocumented. r208028 (uqs): mdoc: move remaining sections into consistent order This pertains mostly to FILES, HISTORY, EXIT STATUS and AUTHORS sections. r209152 (kientzle): If the compressed data is larger than the uncompressed, report the compression ratio as 0% instead of displaying nonsense triggered by numeric overflow. This is common when dealing with uncompressed files when the I/O blocking causes there to be small transient differences in the accounting. r210720 (joel): Fix typos. r223541 (kientzle): If there is a read error reading Y/N confirmation from the keyboard, exit immediately with an error. If there is an error opening or reading a file to put into the archive, set the return value for a deferred error exit. r223573 (kientzle): The --newer-than test should descend into old directories to look for new files. r226636 (kientzle): Typo from previous commit.
