Action create index for a gzip from STDIN not working

Hello, thanks for maintaining this amazing tool :)

I need to use the reading from stdin feature, but is not working anymore for version 1.5.0. I tried for version 1.4.3 and is working fine.

Steps to reproduce:

$ git clone https://github.com/circulosmeos/gztool.git
$ git fetch
$ git checkout v1.5.0
$ automake --add-missing && autoreconf && ./configure && make check
$ cat tests/gplv3.txt.gz | ./gztool -I index.bin
ACTION: Create index for a gzip file

Processing STDIN ...
Processing index to 'index.bin'...
ERROR: Compressed data error in STDIN.
$ make clean
$ git checkout v1.4.3
$ automake --add-missing && autoreconf && ./configure && make check
$ cat tests/gplv3.txt.gz | ./gztool -I index.bin
ACTION: Create index for a gzip file

Index file 'index.bin' already exists and will be used.
Processing STDIN ...
Processing index to 'index.bin'...
$ ./gztool -ell index.bin
ACTION: Check & list info in index file

Checking index file 'index.bin' ...
    Size of index file (v1)  : 84.00 Bytes (84 Bytes)
    Number of index points   : 1
    Size of uncompressed file: 31.27 kiB (32024 Bytes)
    Number of lines          : 207
    Compression factor       : Not available
    List of points:
    #: @ compressed/uncompressed byte L#line_number (window data size in Bytes @window's beginning at index file), ...
#1: @ 20 / 0 L1 ( 0 @60 ), 

1 files processed

Thank you!
