Upstream patch https://gerrit-review.googlesource.com/c/plugins/gitiles/+/163611
Visiting a Gitiles landing page like https://gerrit.wikimedia.org/g/mediawiki/extensions/SyntaxHighlight_GeSHi gives me an SSH clone URL like git clone ssh://gerrit.wikimedia.org:29418/mediawiki/extensions/SyntaxHighlight_GeSHi which is just not very useful. It should use the anonymous HTTPS URL (like git clone "https://gerrit.wikimedia.org/r/mediawiki/extensions/SyntaxHighlight_GeSHi"), or both. Compare https://gerrit.wikimedia.org/r/admin/projects/mediawiki/extensions/SyntaxHighlight_GeSHi which has those options.
(If the SSH URL is kept it should made easier to use - that's T189182: Gitiles should add username in git clone links, triggers "Permission denied (publickey)" error.)
