That means you are using gnu-win32 grep. Some older (2.5.4) and newer 
(2.6.3) cygwin greps won't work.

I don't believe cygwin grep (and other app) is going to be fixed/coded 
like (gnu-win32 app), because it's a matter how arguments are passed 
through winapi->cygwin (whole system) layers.

Besides, older (2.5.x) greps doesn't correctly color (multibyte) matches 
(try grep -nH -e 'Ш*' 6546.txt)
