[Bug 1303757] Re: Gedit violates security of backup file on NTFS

[UlfZibis]

The only thing special is that gedit provides a backup of the original file.
I came to the issue when trying a patch to ntfs-3g were the behaviour to the permissions was contrary, see: http://tuxera.com/forum/viewtopic.php?p=38209&sid=a9914342b2b56a46a33fa94b68d72d15#p38209
In that case the permissions of the backup file remained in correct inherited state, but the regular file got changed permissions, not inherited from the parent folder. So it's unclear, if gedit renames the old file and writes the changes in a new file with original name or if it copies the original to the backup file and changes the content of the original file.
This triggered me to check the behaviour without the patch with an empty file, created from Windows.
