+ *    Revision 1.8  2001/07/30 22:08:36  jongfoster
+ *    Tidying up #defines:
+ *    - All feature #defines are now of the form FEATURE_xxx
+ *    - Permanently turned off WIN_GUI_EDIT
+ *    - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ *    Revision 1.7  2001/07/20 19:29:25  haroon
+ *    - In v1.5 forgot to add that I implemented LOG_LEVEL_POPUPS in errlog.c,
+ *      errlog.h and killpopup.c. In that case, it is superfluous to have define for
+ *      POPUP_VERBOSE, so I removed the defines and logging is now done
+ *      via log_error(LOG_LEVEL_POPUPS, ....)
+ *
+ *    Revision 1.6  2001/07/19 19:11:35  haroon
+ *    - Implemented Guy's idea of replacing window.open( with 1;''.concat(
+ *    - Implemented Guy's idea of replacing .resizeTo( with .scrollTo(
+ *
+ *    Revision 1.5  2001/07/18 15:02:52  haroon
+ *    improved nuking of window.open
+ *
+ *    Revision 1.4  2001/06/29 13:29:55  oes
+ *    Added FIXMEs (and didn't repair, hehe)
