How to exclude certain directories/files from git grep search

Question

Is there a way to exclude certain paths/directories/files when searching a git repository using git grep? Something similar to the --exclude option in the normal grep command?

I need to use git grep because using grep directly runs too slowly on large git repositories.

It's not possible, but has been discussed recently. Proposed workaround in link:

You can put *.dll to .gitignore file then git grep --exclude-standard.

EDIT see onlynone's answer, since git 1.9.0 it's possible.
