(assuming this fixes the issue in question) please amend the commit title to be Fix issue 14543: <issue title goes here> so the bot picks it up properly.

@jamesragray Simply changing the title will not get the bot to pick this up. You need to make a new commit that contains "Fix Issue 14543" in its commit message so that the bot knows to close the bugzilla entry automatically and so that you get bugzilla points that you can see on the leaderboards [1][2] (you can even win prizes, for more info check this blog post[3]). You need to:

git commit --amend -m "Fix Issue 14542 - std.algorithm.searching.until does not handle range sentinels nicely"
git push $your_branch $your_remote_repo
