This makes '-U, --unzcrash' about two times faster +on my machine on files with an uncompressed size larger than about 30 MB. + +'-W, --debug-decompress' now continues decompressing the members following +the damaged member if it has been fully decompressed (just failed with a CRC +mismatch). + +The tool unzcrash now uses execvp instead of popen to avoid invoking /bin/sh +and run faster. It also prints byte or block position in messages. + +Several descriptions have been improved in manual, '--help', and man page. + +The texinfo category of the manual has been changed from 'Data Compression' +to 'Compression' to match that of gzip.
