Changes in version 1.18:

The option "-a, --trailing-error", which makes lzip exit with error
status 2 if any remaining input is detected after decompressing the last
member, has been added.

Decompression time has been reduced by 2%.

The new chapter "Trailing data" has been added to the manual.

Fixed a harmless check failure on Windows caused by the failed
comparison of a message in text mode.
