Changes in version 1.12:

Lunzip now reports an error if a file name is empty (lunzip -t "").

Option '-o, --output' now behaves like '-c, --stdout', but sending the
output unconditionally to a file instead of to standard output. See the new
description of '-o' in the manual. This change is backwards compatible only
when decompressing from standard input alone. Therefore commands like:
  lunzip -d -o foo - bar.lz < foo.lz
must now be split into:
  lunzip -d -o foo - < foo.lz
  lunzip -d bar.lz
or rewritten as:
  lunzip -d - bar.lz < foo.lz > foo

Lunzip now does not even open the output file if the input file is a terminal.

The words 'decompressed' and 'compressed' have been replaced with the
shorter 'out' and 'in' in the verbose output when decompressing or testing.

Option '--list' now reports corruption or truncation of the last header in a
multimenber file specifically instead of showing the generic message "Last
member in input file is truncated or corrupt."

The commands needed to extract files from a tar.lz archive have been
documented in the output of '--help' and in the man page.

9 new test files have been added to the testsuite.
