Ah! So, the make-backup-file-name-function can be used only if
version-control is not set? Didn't know that.. I am here trying to use
version-control set to t, along with a custom
make-backup-file-name-function (for creating a shadow directory
structure for backup files: backup-alist flattens out backup file
names within it.. files like..
~/.emacs.d/backup/home/ramk/.emacs.~2~). Could this then become a
feature request, to allow customization of the backup function for
versioned backups?
