bug#23763: Bug report: Grep stops, if a text file contains a null character after 32768 bytes

[Bjoern Voigt]

What about the inconsistent output?

Grep should not print a mixture of text matches and then exits with a
binary match and exit code 0:

# ./null-bug-testcase.txt
[...]
A
A
A
Binary file testfile.txt matches
Exit code of grep: 0

This is clearly a bug in my eyes.

Is a patch welcome, which fixes this inconsistency? Currently I am
analyzing grep in debugging sessions.
