Changes in version 1.19:

'--merge' is now able to fix files with thousands of scattered errors
per member by grouping the errors into clusters and then merging the
files as if each cluster were a single error.

The option '-a, --trailing-error' now works with '-l, --list' and
'-D, --range-decompress'.

The output of option '-l, --list' has been simplified to make it easier
to read.

In test mode, lziprecover now continues checking the rest of the files
if any input file is a terminal.

Trailing data are now shown both in hexadecimal and as a string of
printable ASCII characters.
