And the rg (ripgrep) manual page says:

  By default, ripgrep attempts to automatically skip binary files in order
to improve the relevance of results and make the search  faster.

And ugrep support -I in with the same meaning as grep.

Thus I propose to add both -I to grep and ugrep, remove the processing of
search output for binary file messages, and extend doc string for users to
be aware that the behavior has (slightly) changed.

I can provide a patch in those lines if needed.
