Agreed.  I was thinking of something along these lines
for -command return code interpretations:

    TCL_OK --
    	Default behavior -- dismiss the dialog if '-persistent false',
	leave it up if '-persistent true'.
    TCL_BREAK --
    	Always dismiss the dialog (overriding '-persistent true')
    TCL_CONTINUE --
    	Always leave the dialog up (overriding '-persistent false')
    TCL_RETURN --
    	(same as TCL_OK?)
    TCL_ERROR --
    	Return the error result to the caller (normally
	the event loop, which will eventually call bgerror).
	Not sure what else should happen -- probably ought
	to release the grab if '-modal true' was set.
    Other --
    	Return the completion code/result/other return options
	to to the caller.
