bug#69929: Can grep -q report matches in incomplete lines?

[David G. Pickett]

 Perhaps the man page should warn users that such last lines are ignored.  Is 
there a mention under an option to include or disclude them?

Well, POSIX doesn't:

The definition may cause trouble with shell's read - e.g. when reading a file 
created on Windows with notepad where it is easy to accidentally create an 
incomplete line (compared to vi where I don't know an easy way).

Best regards,
