But this is neither a bug of Tramp nor of the grep command. The error
message "fatal: '/dev/null' is outside repository" comes from git.
As you have said the other message, /dev/null is added due to the
setting of grep-use-null-device. This is computed according to the needs
of grep, and not of git.
So I wouldn't regard this as an error.
Best regards, Michael.
