Finish off the indentation cleanup. Add new '--width' and '--height'

2003-04-13  Glynn Foster  <glynn.foster@sun.com>

	* src/calendar.c, src/entry.c, src/fileselection.c,
	src/main.c, src/msg.c, src/progress.c, src/text.c,
	src/tree.c, src/zenity.h: Finish off the indentation cleanup.
	Add new '--width' and '--height' options to the general options.
	Fix up the radio list view, so that we can now act like a radio
	button group.

	* TODO: Update
