[Bug 1665365] [NEW] grep switch -v does not emit expected rows. LANG=C or upgrade to 2.9 solve problem

[marco vaccari]

Public bug reported:

Description:	Ubuntu 16.04.1 LTS
Release:	16.04

grep:
  Installato: 2.25-1~16.04.1
  Candidato:  2.25-1~16.04.1

On very long file generated using util find (in a large system automatic backup procedure).
1) switch -v exclude random rows not matching regular expression
2) grep declare "binary" the text file ("binary file xxx match")
3) Without -v switch rows are correctly selected

LANG=it_IT.UTF-8

apparently SOLVED with:
LANG=C egrep ....

or upgrading to 2.9 from GNU repository.

Cannot replicate bug with simple forged text file.
