	* app/fileops.c
	* libgimp/gimpquerybox.[ch]: Make sure that we don't try to destroy
	query_boxes twice or try to disconnect not-any-more connected
	handlers.

	* app/color_notebook.c
	* app/gimpcontext.[ch]
	* app/gimphelp.[ch]
	* app/lc_dialog.[ch]
	* app/menus.h
	* app/preferences_dialog.c
	* app/tools.[ch]
	* libgimp/gimpcolorbutton.[ch]
	* libgimp/gimpdialog.[ch]
	* libgimp/gimpexport.[ch]
	* libgimp/gimpfileselection.[ch]
	* libgimp/gimphelpui.[ch]
	* libgimp/gimppatheditor.[ch]
	* libgimp/gimppixmap.[ch]
	* libgimp/gimpsizeentry.[ch]
	* libgimp/gimpui.[ch]
	* libgimp/gimpunitmenu.[ch]
	* libgimp/gimpwidgets.[ch]: in a coding attack, changed help_data
	and many other strings passed to UI functions to (const gchar *).
	As a consequence, I had to fix lots of warnings ;)

	* plug-ins/common/tga.c
	* plug-ins/imagemap/imap_main.c: fixed warnings.

	Code cleanup and indentation all over the place.
