mrg 60c6cf919b port across the change from freebsd rev 290024: 
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.

christos d6eaf99167 Coverity CID 1264915, Via FreeBSD (Xin Li) 
When reading in the original file name from gzip header, we read
in PATH_MAX + 1 bytes from the file.  In r281500, strrchr() is
used to strip possible path portion of the file name to mitigate
a possible attack.  Unfortunately, strrchr() expects a buffer
that is NUL-terminated, and since we are processing potentially
untrusted data, we can not assert that be always true.

Solve this by reading in one less byte (now PATH_MAX) and
explicitly terminate the buffer after the read size with NUL.

invoked with a pathname (ie, /usr/bin/z{e,f}grep).

nakayama 66f1c31a47 grep "-H" option (print the filename for each match) always prints 
filenames whether "-h" option (suppress filenames when multiple files
are searched) is speficied or not.

Make zgrep "-h" option actually works with using "-H" option only
when "-h" is not specified.
