bug#24347: Bug when grepping a text file with some arbitrary binary data

[Alexey Dubovkin]

Hello,

Please consider to fix a bug. I'd found it while parsing my huge logs and I
was able to localize it to grep's version and small test file

*Affected versions:*
v2.23 - v2.25 && recent master

Steps to reproduce (use the attached test file):
./grep 31325 test

*Actual result:*
08-31 17:59:47.844 31325 31398 I ServerResponse2: [afm::msg] parse():
parse bytes, salt=qpih6vh1ck, decoded:
Binary file test matches

*Expected result:*
A full output of the test file since all lines matches 31325

The versions v2.22 and below are not affected and produces the full file
output as expected

Thank you!

Regards,
Alex
