[PATCH] grep directory loop reporting outputs extra newline

[Andre Guibert de Bruet]

Hi,

I noticed a simple output regression between 4.10 and CURRENT wrt grep's 
output when it encounters a recursive directory loop. CURRENT puts an 
extra new-line when such a path is found. This adds complexity to scripts 
that rely on the traditional way of doing things.

The patch attached to this email can also be found at:

Could this be committed?

Thanks,
Andy
