  Message : Fix the zran.c example to work on a multiple-member gzip file.

• examples/README.examples

• This directory contains examples of the use of zlib and other relevant
  programs and documentation.
  
  enough.c
      calculation and justification of ENOUGH parameter in inftrees.h
      - calculates the maximum table space used in inflate tree
        construction over all possible Huffman codes
  
  fitblk.c
      compress just enough input to nearly fill a requested output size
      - zlib isn't designed to do this, but fitblk does it anyway
  
  gun.c
      uncompress a gzip file
      - illustrates the use of inflateBack() for high speed file-to-file
        decompression using call-back functions
      - is approximately twice as fast as gzip -d
      - also provides Unix uncompress functionality, again twice as fast
  
  gzappend.c
      append to a gzip file
      - illustrates the use of the Z_BLOCK flush parameter for inflate()
      - illustrates the use of deflatePrime() to start at any bit
  
  gzjoin.c
      join gzip files without recalculating the crc or recompressing
      - illustrates the use of the Z_BLOCK flush parameter for inflate()
      - illustrates the use of crc32_combine()
  
  gzlog.c
  gzlog.h
      efficiently and robustly maintain a message log file in gzip format
      - illustrates use of raw deflate, Z_PARTIAL_FLUSH, deflatePrime(),
        and deflateSetDictionary()
      - illustrates use of a gzip header extra field
  
  gznorm.c
      normalize a gzip file by combining members into a single member
      - demonstrates how to concatenate deflate streams using Z_BLOCK
  
  zlib_how.html
      painfully comprehensive description of zpipe.c (see below)
      - describes in excruciating detail the use of deflate() and inflate()
  
  zpipe.c
      reads and writes zlib streams from stdin to stdout
      - illustrates the proper use of deflate() and inflate()
      - deeply commented in zlib_how.html (see above)
  
  zran.c
  zran.h
      index a zlib or gzip stream and randomly access it
      - illustrates the use of Z_BLOCK, inflatePrime(), and
        inflateSetDictionary() to provide random access
