Strange behaviour with repo regex query

Created by: aboulart

Both on my local docker instance, and on the public sourcegraph.com search, I see weird behaviour when doing regex paren searches on repos.

The query above doesn't return any results. If I remove the '.*', it returns results from golang/oauth2:

I would expect both queries to return the same results from the golang/oauth2 repo. Am I doing something wrong?

Thanks!
