Changes in version 1.18:

"--repair" now tries to detect gross damage in the file before
attempting to repair it.

"--repair" now tries bytes at member offsets 7 and 8 first because
errors in these bytes sometimes can't be detected until the end of the
member.

The new option "-x, --show-packets", which shows the LZMA packets
(coding sequences) coded in a given file, has been added.
