What's new?

• support the latest bzip3 library upgrades #446 *)
• permit su search of "unreadable" files #447
• do not exit with code 2 when some files can't be decompressed #448

*) please note that./build.sh --with-bzip3 or ./configure --with-bzip3 && make enables bzip3 in ugrep, when libbzip3 is present and found, otherwise ugrep and the indexer skip bz3 files; for help with configuration, run ./build.sh --help

Thank you for your feedback to help improve ugrep for everyone!
