See vc-version-backup-file-name. They are created the first time the
modified file is saved.
This is not happening for me when I edit the Emacs sources.
The reason seems to be that
(vc-call-backend backend 'make-version-backups-p file)
does nothing, because it calls vc-default-make-version-backups-p
which always returns nil.
This is because (get 'Bzr 'vc-functions)
returns the following:
((make-version-backups-p vc-default-make-version-backups-p . Bzr) (checkout-model . vc-bzr-checkout-model) (registered . vc-bzr-registered) (find-file-hook . vc-bzr-find-file-hook) (working-revision . vc-bzr-working-revision) (state-heuristic . vc-bzr-state-heuristic) (mode-line-string vc-default-mode-line-string . Bzr))
Indeed, vc-bzr-make-version-backups-p is not defined.
Should it be?
