maybe a bird shape for gerrit in specific or something generic representing "code-review"
Maybe the glasses icon would work ("proof-reading")?
Or playlist-check, as the lines could be interpreted as text in general.
Put this together, not too bad: 
@CoDEmanX I like that one. Nice and generic could work for a few uses.
code-tags-check

Also work as icon for code validation (e.g. XML well-formedness)
looks awesome!
