backup-by-copying-when-privileged-mismatch applies to file gid, too.
* lisp/files.el (backup-by-copying-when-privileged-mismatch): In addition to checking the file uid, a second test is added: if the file gid is not greater than backup-by-copying-when-privileged-mismatch, backup-by-copying-when-mismatch will also be forced on. * doc/emacs/files.texi, doc/lispref/backups.texi: Updated documentation. Also fixed a typo in the Emacs reference manual, changing "higher" to "no greater" so that the limit is no longer documented reversed.

@defopt backup-by-copying-when-privileged-mismatch
This variable, if non-@code{nil}, specifies the same behavior as
