Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove code duplication by unifying the certificatelist. You should now check for isInstallCert to determine wether this certificate should be installed or removed. Leaving the getInstallCertificates and getRemoveCertificates in place for compatibilty would have been easier to keep the tests stable.
