CVS commit: src/usr.bin/gzip

[matthew green <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg
Date:           Tue May 25 04:34:40 UTC 2004

Modified Files:
        src/usr.bin/gzip: gzip.c unbzip2.c zuncompress.c

Log Message:
- fix "gzip -t" to not output anything by default.  PR#25507
- fix any decompression on corrupted gzip files.  PR#25508
- ask to overwrite files if we have a tty, rather than failing the
  operation.  PR#25509.
- clean up maybe_err()/maybe_warn(): use maybe_err() only for fatal
  errors.  maybe_warn() is for processing errors.  this allows
  "gzip -d file1.gz file2.gz" to decompress file2.gz even if file1.gz
  is corrupted, etc.
- change the internal compressor/decompressor API to return "-1" on
  failure, not 0.  this allows for 0-sized files to be decompressed
  correctly.
