Which test result do you get for the command example

matched tab characters?
Not with that test case, no. There is no color information at all. grep's
--color option was not used.
A similar clarification attempt resulted in a bit of better understanding

That's a long page, which I don't have the patience to read to the end. As near
as I can make out, the basic problem is that you didn't understand how grep is
supposed to work, and reported its behavior as a bug. However, as far as I can
see from the above example, grep is working as specified.
