Hello,

After upgrading to V2.21 I discovered that certain textfiles did not
yield any output after a grep search but the single line:

Binary file <NAME_FILE> matches

Further tests showed, that grep only behaved this way with text
files that were encoded according to ISO-8859 (There may be more!).
The presence or absence of diacritical characters didn't matter, nor
variants of formatting; another file with DOS type <CR><LF>'s parsed
just the same.

The only way to overcome this was by using the `roughshod' option
of the -a flag.

None of grep's versions that I have used before ever showed
this peculiarity.

I hope you can shed some light on this issue,

hansp

I installed into Savannah a patch (attached) that should fix this problem in 
typical cases, and am boldly marking the bug as done. Please give the fix a try 
if you have the time. Thanks.
