-The option "-a, --trailing-error", which makes pdlzip exit with error
-status 2 if any remaining input is detected after decompressing the last

+In test mode, pdlzip now continues checking the rest of the files if any

-When decompressing, the file specified with the '--output' option is now
-deleted if the input is a terminal.

-A harmless check failure on Windows, caused by the failed comparison of
