disklabel: delete a partition?

[Ede Wolf <listac%nebelschwaden.de@localhost>]

Hello,

I have two partitions, sd0e and sd0f, that I would like to merge into a 
single, large partition, presumibly a larger sd0e. Both are empty.

However, using disklabel, I am not able to find a way to delete both to 
recreate sd0e.

Even, when setting sd0f as type "unsused", it asks for start and end 
sectors, which of course are not available, as sd0e will take up all 
remaining space.

Any other tool I might overlook? Not additional GPT or MBR present, 
plain, good(?) ole  disklabel.

Thanks

Ede
