When this is reviewed, could you `/integrate defer` it so that I can control when it gets integrated? I will need to prepare a patch for dependent internal source that has to go in at the same time.

I get why you want this method for symmetry, but in reality we could never actually call it in Skara if it would actually return all pull requests for a repo. The potential result set is just too large. The JDK repo has over 10k already. This is why the old `pullRequests(ZonedDateTime)` has the maxPages(1) limit. This method needs that too.

I don't think we need this comment. Same for lines 181:182.

forge/src/main/java/org/openjdk/skara/forge/gitlab/GitLabRepository.java line 135:

We need a maxPages limit here too. I see it's missing for pullRequestsAfter for Gitlab as well, which is a bug and should also be fixed.
