+ *
+ * This fixes an issue in GOutputStream that applies the atomic replace
+ * save strategy. The stream moves the written file to the original file
+ * when the stream is closed. However, there is no way currently to tell
+ * the stream that the save should be aborted (there could be a
+ * conversion error). The patch explicitly closes the output stream
+ * in all these cases with a GCancellable in the cancelled state, causing
+ * the output stream to close, but not move the file. This makes use
+ * of an implementation detail in the local gio file stream and should be
+ * properly fixed by adding the appropriate API in gio. Until then, at least
+ * we prevent data corruption for now.
+ *
+ * Relevant bug reports:
+ *
+ * Bug 615110 - write file ignore encoding errors (gedit)
+ * https://bugzilla.mate.org/show_bug.cgi?id=615110
+ *
+ * Bug 602412 - g_file_replace does not restore original file when there is
+ *              errors while writing (glib/gio)
