C-h-v backup-by-coping gives me:
"backup-by-copying's value is nil"
Which, I assume, means that Emacs might use renaming for backups.
And C-h-v backup-by-coping-when-mismatch results in:
"backup-by-copying-when-mismatch's value is nil"
I guess if this value would be non-nil, my problem would be solved?
Additionally, C-h-v backup-by-copying-when-privileged-mismatch gives me:
"backup-by-copying-when-privileged-mismatch's value is 200"
I just toggled backup-by-copying-when-mismatch and tried it again, and
indeed, it does work now.
I'm just wondering if this means that the default behavior is broken?
It seems Emacs automatically sets backup-by-copying-when-mismatch to t
when it is run by the superuser (root) to overcome this problem
(source: http://www.delorie.com/gnu/docs/emacs/emacs_117.html).
I don't think many people will run Emacs as root in this day and age.
However, they might log in as root on a remote server, or edit a file
as root (using sudo/su). Maybe Emacs or Tramp should also
automatically set the backup-by-copying-when-mismatch variable to t in
those cases?
Thanks for your help!
Cheers,
