[Qt-interest] QSettings, linux, overwties backup files?

[ext-butch.howard at nokia.com]

I am using QSettings to read and write files in the QSettings::IniFormat. I noticed that when there is also a file in the folder created by vi as as backup ( i.e. settings.ini~ ) that this backup file will get overwritten with the content of the QSettings when it writes the settings.ini file.  If the vi backup file does not exist in the folder at the time QSettings writes the settings file, a backup file is not created (or at least not left around when it is finished).

Is this behavior of overwriting a file in the backup-filename-format ( NAME~ ) expected? Is it some unintended side affect of some of the file save/sync processing?
