Thanks for your quick reaction Yuval.

No that is not correct (Vista will not even install into less than 16 
MB :-)

From the log:
Current volume size: 20972564992 bytes (20973 MB)
Current device size: 20972568576 bytes (20973 MB)

/dev/sda1   *           1        2550    20481024    7  HPFS/NTFS

That is the same in both cases.

Hmm. I did not note anything about that in the FAQ (happy to be proven 
wrong), and it still feels like a regression because with NTFS 1.2 my 
method did work correctly. However, I will give it a try.

It also feels strange because I did not change the starting sector and the 
end sector was well bigger than the new size of the NTFS partition.

Also note that it means that 2 major linux partitioning tools (fdisk and 
parted) would be wrong.

Ah, I see 1.13.1 has just hit unstable. I will test with that and let you 
know.
