git grep filters its output through the program set in the environment variable GIT_PAGER, so you just need to set that variable to an appropriate pager. Or, set your environment so that the pager it uses exhibits the behavior you want. For example, either GIT_PAGER="less -S" or LESS=-S should work (assuming your default PAGER is less). You need to put those in the environment, so you might either put export GIT_PAGER or export LESS in your shell startup scripts, or run GIT_PAGER="less -S" git grep ...
