The stricter parsing of ssh password prompts causes another regression for mercurial users, see https://bugs.kde.org/show_bug.cgi?id=380085
This is similar to https://phabricator.kde.org/D4540 for bug 376228, which fixed the issue for git users.
I also removed the "Case" numbering from the fallback warning, because it causes confusing diffs, as seen here.
