[Orgmode] indentation problem

[Rainer Stengele]

I have a minor indentation quirk:

Orgmode does not allow to indent the ":END:" symbol correctly.
Indenting the while block beginning from the headline down to :END: does not 
change anything here.

Is this a (minor) bug?

Ahh - putting the block in a separate file does the correct indentation.
But why? Is the indentation mechnism dependant on the previous blocks?
