face customization saves custom-file twice

[David PONCE <david.ponce@wanadoo.fr>]

Hi,

After I customized a face via M-x customize-face and clicked on the
"State" button, "Save for Future Sessions" menu item, I noticed that
my `custom-file' has been saved twice.  And because of that I lost the
backup copy of `custom-file'!

I suspect that the problem is in one of the functions:
`custom-face-save-command' which calls `custom-face-save', both
calling `custom-save-all'.

I suppose it should be safe to remove the call to `custom-save-all'
from `custom-face-save-command'?

However I prefer to let a custom guru fix that ;-)

Sincerely,
David
