Issue #9790 has been updated by jeremyevans0 (Jeremy Evans).

File zlib-gzreader-each_file-9790.patch added

Attached is a patch that adds `Zlib::GzipReader.each_file` will which handle multiple concatenated gzip streams in the same file, similar to common tools that operate on `.gz` files.  `Zlib::GzipReader.each_file` yields one `Zlib::GzipReader` instance per gzip stream in the file.

Bug #9790: Zlib::GzipReader only decompressed the first of concatenated files

----------------------------------------
There is a similar old issue in Node that I came across that perfectly describes the situation in ruby:

https://github.com/joyent/node/issues/6032

In ruby given the following setup:

```
echo "1" > 1.txt
echo "2" > 2.txt
gzip 1.txt
gzip 2.txt
cat 1.txt.gz 2.txt.gz > 3.txt.gz
```

Calling:
    
```
Zlib::GzipReader.open("3.txt.gz") do |gz|
  print gz.read
end
```

would just print:

```
1
```
