Since bonobo doesn't seem to O_TRUNC the file stream before writing to it,
2002-04-08 Jeffrey Stedfast <fejj@ximian.com> * mail-signature-editor.c (menu_file_save_cb): Since bonobo doesn't seem to O_TRUNC the file stream before writing to it, write to a temp file first and then rename() it to the real filename. This also protects against losing data if the drive is full too. Also use a real mode, not 0, so that we can actually save/read the content ;-) svn path=/trunk/; revision=16392
