Patch Set 3:

that's a very useful enhancement !

some remarks after playing a bit (not thoroughly tested yet):
- results should be grouped by repository
- search hits should be highlighted in commit viewer, so that I can see where my search term has been found
- is there a way to display which branches contain a given commit returned in the result list? 
- the result list header could list a short summary of the search criteria
- there should be an option (which should be on by default) to reuse the commit viewer views so that after having navigated a long list of results I don't end up with zillions of open commit views
