Currently the go.dev/cl/... redirect doesn't support patchset syntax, i.e. go.dev/cl/c/1234/5. This breaks some tooling, like Linkable, which generate shortened URLs using the typical Gerrit syntax (the assumption being that go.dev/cl/c/1234/5 will redirect to go-review.googlesource.com/c/1234/5) if you are trying to link to a specific patchset.

Dmitri suggested in http://go.dev/cl/396494 that we support linking to patchsets, but without the extra /c/ prefix that Gerrit uses (i.e. we'd redirect from go.dev/cl/1234/5 to go-review.googlesource.com/c/1234/5) which seems reasonable. This would require fixing how tooling like Linkable generate their shortened links, but that seems fine.
