`[ci skip]` does not work in Pull Requests

[slfritchie]

Today I’d created two GitHub pull requests with “[skip ci]” and “[ci skip]” in their initial commit messages. Both of them triggered Circle-CI tests, something I didn’t expect.

• WallarooLabs/wallaroo/pull/1976
  • Circle-CI test results: https://circleci.com/gh/WallarooLabs/wallaroo/165?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link
• WallarooLabs/wallaroo/pull/1977
  • https://circleci.com/gh/WallarooLabs/wallaroo/170?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link

Both PRs have later commits that include the skip text in various places within the commit message … but all subsequent commits did skip Circle-CI’s tests. That’s good, but it would be even better to skip when requested the first time also.
