@takeshitakenji I don't understand what would've caused an internal server error, especially only for local users. And I don't immediately see the practical change in the regex. You replaced the initial bit with a negative lookback for non-whitespace and then seemingly simplified the user-part (which is of course good and I think I'll copy).

@takeshitakenji I've even replied to you, so I obviously don't block: https://gs.kawa-kun.com/notice/1556135
