No, it's the (hopefully) tried and true `ediff-truncate-string-left',
only renamed and moved to subr-x to be generally available. The changes
are cosmetic. It would even be possible (in emacs-27, to avoid moving
anything), to use `ediff-truncate-string-left' unchanged, but that would
require gnus-sum to (require 'ediff-init), which would be crazy. Or make
`ediff-truncate-string-left' a defsubst instead of defun and
(eval-when-compile (require 'ediff-init)) in gnus-sum. That should
actually work :-P

Thanks.
