(just for the records) :)
*sorting* works in any case!!! according to the manual sorting actually
is ok. the documentation says *nothing* about the keys (de facto, if you
would weigh this behaviour against the documentation you would not be
able to find a bug anyhow) it just is a kind of inconsistency. you only
can treat this a bug looking at the C code, where a parameter for
"renumbering" is given (renumbering is 0 for key-preserving sorting)
the current behaviour simply isn't defined and thus follows: you can
infer anything from a wrong premise! inferring this being correct
behaviour is equally legitimate inferring the contrary!
actually I think treating this as a bug makes sense, but this should not
go in before 4.1 to avoid any confusion.
