From having a look at where this function is used, by Geany it's used only to store configuration files in the .config directory and some auxiliary functions like writing the export file by the exporter plugin. In the geany-plugins project this function is used only for saving configuration files.
Before this patch, the fwrite() method was used by default for saving configuration files (because g_file_replace_contents() normally used by Geany wasn't used in this function) which wasn't very safe and could lead to configuration file loss under some extreme conditions.
The documentation of this function was changed to reflect the situation better than now - the previous comment made the impression that file permissions were always preserved with this method but it wasn't the case and depended on the exact configuration.
